CPACK-GENERATORS(7)

NAME
cpack-generators - CPack Generator Reference

GENERATORS

  CPack Archive Generator

CPack generator for packaging files into an archive, which can have any of the following formats:

•   7Z - 7zip - (.7z)

•   TBZ2 (.tar.bz2)

•   TGZ (.tar.gz)

•   TXZ (.tar.xz)

•   TZ (.tar.Z)

•   TZST (.tar.zst)

•   ZIP (.zip)

    When this generator is called from CPackSourceConfig.cmake (or through the package_source target), then the generated archive will contain all files in the project directory, except those specified in CPACK_SOURCE_IGNORE_FILES. The following is one example of packaging all source files of a project:

    set(CPACK_SOURCE_GENERATOR "TGZ")
    set(CPACK_SOURCE_IGNORE_FILES
      \\.git/
      build/
      ".*~$"
    )
    set(CPACK_VERBATIM_VARIABLES YES)
    include(CPack)

    When this generator is called from CPackConfig.cmake (or through the package target), then the generated archive will contain all files that have been installed via CMake’s install() command (and the deprecated commands install_files(), install_programs(), and install_targets()).

  Variables specific to CPack Archive generator

CPACK_ARCHIVE_FILE_NAME

CPACK_ARCHIVE_<component>_FILE_NAME
    Package file name without extension. The extension is determined from the archive format (see list above) and automatically appended to the file name. The default is <CPACK_PACKAGE_FILE_NAME>[-<component>], with spaces replaced by ‘-‘.

CPACK_ARCHIVE_COMPONENT_INSTALL
    Enable component packaging. If enabled (ON), then the archive generator creates multiple packages. The default is OFF, which means that a single package containing files of all components is generated.

  Variables used by CPack Archive generator

These variables are used by the Archive generator, but are also available to CPack generators which are essentially archives at their core. These include:

•   CPack Cygwin Generator

•   CPack FreeBSD Generator

CPACK_ARCHIVE_THREADS
    The number of threads to use when performing the compression. If set to 0, the number of available cores on the machine will be used instead. The default is 1 which limits compression to a single thread. Note that not all compression modes support threading in all environments. Currently, only the XZ compression may support it.

    NOTE: Official CMake binaries available on cmake.org ship with a liblzma that does not support parallel compression.

  CPack Bundle Generator

CPack Bundle generator (macOS) specific options

  Variables specific to CPack Bundle generator

Installers built on macOS using the Bundle generator use the aforementioned DragNDrop (CPACK_DMG_xxx) variables, plus the following Bundle-specific parameters (CPACK_BUNDLE_xxx).

CPACK_BUNDLE_NAME
    The name of the generated bundle. This appears in the macOS Finder as the bundle name. Required.

CPACK_BUNDLE_PLIST
    Path to an macOS Property List (.plist) file that will be used for the generated bundle. This assumes that the caller has generated or specified their own Info.plist file. Required.

CPACK_BUNDLE_ICON
    Path to an macOS icon file that will be used as the icon for the generated bundle. This is the icon that appears in the macOS Finder for the bundle, and in the macOS dock when the bundle is opened. Required.

CPACK_BUNDLE_STARTUP_COMMAND
    Path to a startup script. This is a path to an executable or script that will be run whenever an end-user double-clicks the generated bundle in the macOS Finder. Optional.

CPACK_BUNDLE_APPLE_CERT_APP
    The name of your Apple supplied code signing certificate for the application. The name usually takes the form Developer ID Application: [Name] or 3rd Party Mac Developer Application: [Name]. If this variable is not set the application will not be signed.

CPACK_BUNDLE_APPLE_ENTITLEMENTS
    The name of the Property List (.plist) file that contains your Apple entitlements for sandboxing your application. This file is required for submission to the macOS App Store.

CPACK_BUNDLE_APPLE_CODESIGN_FILES
    A list of additional files that you wish to be signed. You do not need to list the main application folder, or the main executable. You should list any frameworks and plugins that are included in your app bundle.

CPACK_BUNDLE_APPLE_CODESIGN_PARAMETER
    Additional parameter that will passed to codesign. Default value: --deep -f

CPACK_COMMAND_CODESIGN
    Path to the codesign(1) command used to sign applications with an Apple cert. This variable can be used to override the automatically detected command (or specify its location if the auto-detection fails to find it).

  CPack Cygwin Generator

Cygwin CPack generator (Cygwin).

  Variables affecting the CPack Cygwin generator

•   CPACK_ARCHIVE_THREADS

  Variables specific to CPack Cygwin generator

The following variable is specific to installers build on and/or for Cygwin:

CPACK_CYGWIN_PATCH_NUMBER
    The Cygwin patch number. FIXME: This documentation is incomplete.

CPACK_CYGWIN_PATCH_FILE
    The Cygwin patch file. FIXME: This documentation is incomplete.

CPACK_CYGWIN_BUILD_SCRIPT
    The Cygwin build script. FIXME: This documentation is incomplete.

  CPack DEB Generator

The built in (binary) CPack DEB generator (Unix only)

  Variables specific to CPack Debian (DEB) generator

The CPack DEB generator may be used to create DEB package using CPack. The CPack DEB generator is a CPack generator thus it uses the CPACK_XXX variables used by CPack.

The CPack DEB generator should work on any Linux host but it will produce better deb package when Debian specific tools dpkg-xxx are usable on the build system.

The CPack DEB generator has specific features which are controlled by the specifics CPACK_DEBIAN_XXX variables.

CPACK_DEBIAN_<COMPONENT>_XXXX variables may be used in order to have component specific values. Note however that <COMPONENT> refers to the grouping name written in upper case. It may be either a component name or a component GROUP name.

Here are some CPack DEB generator wiki resources that are here for historic reasons and are no longer maintained but may still prove useful:

•   https://gitlab.kitware.com/cmake/community/-/wikis/doc/cpack/Configuration

•   https://gitlab.kitware.com/cmake/community/-/wikis/doc/cpack/PackageGenerators#deb-unix-only

    List of CPack DEB generator specific variables:

CPACK_DEB_COMPONENT_INSTALL
    Enable component packaging for CPackDEB

•   Mandatory : NO

•   Default : OFF

    If enabled (ON) multiple packages are generated. By default a single package containing files of all components is generated.

CPACK_DEBIAN_PACKAGE_NAME

CPACK_DEBIAN_<COMPONENT>_PACKAGE_NAME
    Set Package control field (variable is automatically transformed to lower case).

•   Mandatory : YES

•   Default :

•   CPACK_PACKAGE_NAME for non-component based installations

•   CPACK_DEBIAN_PACKAGE_NAME suffixed with -<COMPONENT> for component-based installations.

    See https://www.debian.org/doc/debian-policy/ch-controlfields.html#s-f-Source

CPACK_DEBIAN_FILE_NAME

CPACK_DEBIAN_<COMPONENT>_FILE_NAME
    Package file name.

•   Mandatory : YES

•   Default : <CPACK_PACKAGE_FILE_NAME>[-<component>].deb

    This may be set to DEB-DEFAULT to allow the CPack DEB generator to generate package file name by itself in deb format:

    <PackageName>_<VersionNumber>-<DebianRevisionNumber>_<DebianArchitecture>.deb

    Alternatively provided package file name must end with either .deb or .ipk suffix.

    NOTE: Preferred setting of this variable is DEB-DEFAULT but for backward compatibility with the CPack DEB generator in CMake prior to version 3.6 this feature is disabled by default.

    NOTE: By using non default filenames duplicate names may occur. Duplicate files get overwritten and it is up to the packager to set the variables in a manner that will prevent such errors.

CPACK_DEBIAN_PACKAGE_EPOCH
    The Debian package epoch

•   Mandatory : No

•   Default : -

    Optional number that should be incremented when changing versioning schemas or fixing mistakes in the version numbers of older packages.

CPACK_DEBIAN_PACKAGE_VERSION
    The Debian package version

•   Mandatory : YES

•   Default : CPACK_PACKAGE_VERSION

    This variable may contain only alphanumerics (A-Za-z0-9) and the characters . + - ~ (full stop, plus, hyphen, tilde) and should start with a digit. If CPACK_DEBIAN_PACKAGE_RELEASE is not set then hyphens are not allowed.

    NOTE: For backward compatibility with CMake 3.9 and lower a failed test of this variable’s content is not a hard error when both CPACK_DEBIAN_PACKAGE_RELEASE and CPACK_DEBIAN_PACKAGE_EPOCH variables are not set. An author warning is reported instead.

CPACK_DEBIAN_PACKAGE_RELEASE
    The Debian package release - Debian revision number.

•   Mandatory : No

•   Default : -

    This is the numbering of the DEB package itself, i.e. the version of the packaging and not the version of the content (see CPACK_DEBIAN_PACKAGE_VERSION). One may change the default value if the previous packaging was buggy and/or you want to put here a fancy Linux distro specific numbering.

CPACK_DEBIAN_PACKAGE_ARCHITECTURE

CPACK_DEBIAN_<COMPONENT>_PACKAGE_ARCHITECTURE
    The Debian package architecture

•   Mandatory : YES

•   Default : Output of dpkg --print-architecture (or i386 if dpkg is not found)

CPACK_DEBIAN_PACKAGE_DEPENDS

CPACK_DEBIAN_<COMPONENT>_PACKAGE_DEPENDS
    Sets the Debian dependencies of this package.

•   Mandatory : NO

•   Default :

•   An empty string for non-component based installations

•   CPACK_DEBIAN_PACKAGE_DEPENDS for component-based installations.

    NOTE: If CPACK_DEBIAN_PACKAGE_SHLIBDEPS or more specifically CPACK_DEBIAN_<COMPONENT>_PACKAGE_SHLIBDEPS is set for this component, the discovered dependencies will be appended to CPACK_DEBIAN_<COMPONENT>_PACKAGE_DEPENDS instead of CPACK_DEBIAN_PACKAGE_DEPENDS. If CPACK_DEBIAN_<COMPONENT>_PACKAGE_DEPENDS is an empty string, only the automatically discovered dependencies will be set for this component.

    Example:

    set(CPACK_DEBIAN_PACKAGE_DEPENDS "libc6 (>= 2.3.1-6), libc6 (< 2.4)")

CPACK_DEBIAN_ENABLE_COMPONENT_DEPENDS
    Sets inter component dependencies if listed with CPACK_COMPONENT_<compName>_DEPENDS variables.

•   CPACK_DEBIAN_<COMPONENT>_DESCRIPTION (component based installers only) if set, or CPACK_DEBIAN_PACKAGE_DESCRIPTION if set, or

•   CPACK_COMPONENT_<compName>_DESCRIPTION (component based installers only) if set, or CPACK_PACKAGE_DESCRIPTION if set, or

•   content of the file specified in CPACK_PACKAGE_DESCRIPTION_FILE if set

    If after that description is not set, CPACK_PACKAGE_DESCRIPTION_SUMMARY going to be used if set. Otherwise, CPACK_PACKAGE_DESCRIPTION_SUMMARY will be added as the first line of description as defined in Debian Policy Manual.

CPACK_DEBIAN_PACKAGE_SECTION

CPACK_DEBIAN_<COMPONENT>_PACKAGE_SECTION
    Set Section control field e.g. admin, devel, doc, …

•   Mandatory : YES

CPACK_DEBIAN_ARCHIVE_TYPE
    The archive format used for creating the Debian package.

•   Mandatory : YES

•   Default : “gnutar”

    Possible value is:

•   gnutar

    NOTE: This variable previously defaulted to the paxr value, but dpkg has never supported that tar format. For backwards compatibility the paxr value will be mapped to gnutar and a deprecation message will be emitted.

CPACK_DEBIAN_COMPRESSION_TYPE
    The compression used for creating the Debian package.

•   Mandatory : YES

•   Default : “gzip”

    Possible values are:

•   lzma

•   Mandatory : NO

•   Default : CMAKE_PROJECT_HOMEPAGE_URL

    NOTE: The content of this field is a simple URL without any surrounding characters such as <>.

CPACK_DEBIAN_PACKAGE_SHLIBDEPS

CPACK_DEBIAN_<COMPONENT>_PACKAGE_SHLIBDEPS
    May be set to ON in order to use dpkg-shlibdeps to generate better package dependency list.

•   Mandatory : NO

•   Default :

•   CPACK_DEBIAN_PACKAGE_SHLIBDEPS if set or

•   OFF

    NOTE: You may need set CMAKE_INSTALL_RPATH to an appropriate value if you use this feature, because if you don’t dpkg-shlibdeps may fail to find your own shared libs. See https://gitlab.kitware.com/cmake/community/-/wikis/doc/cmake/RPATH-handling

CPACK_DEBIAN_PACKAGE_DEBUG
    May be set when invoking cpack in order to trace debug information during the CPack DEB generator run.

•   Mandatory : NO

•   Default : -

CPACK_DEBIAN_PACKAGE_PREDEPENDS

CPACK_DEBIAN_<COMPONENT>_PACKAGE_PREDEPENDS
    Sets the Pre-Depends field of the Debian package. Like Depends, except that it also forces dpkg to complete installation of the packages named before even starting the installation of the package which declares the pre-dependency.

•   Mandatory : NO

•   Default :

•   An empty string for non-component based installations

•   CPACK_DEBIAN_PACKAGE_PREDEPENDS for component-based installations.

    See http://www.debian.org/doc/debian-policy/ch-relationships.html#s-binarydeps

CPACK_DEBIAN_PACKAGE_ENHANCES

CPACK_DEBIAN_<COMPONENT>_PACKAGE_ENHANCES
    Sets the Enhances field of the Debian package. Similar to Suggests but works in the opposite direction: declares that a package can enhance the functionality of another package.

•   Mandatory : NO

•   Default :

•   An empty string for non-component based installations

•   CPACK_DEBIAN_PACKAGE_ENHANCES for component-based installations.

    See http://www.debian.org/doc/debian-policy/ch-relationships.html#s-binarydeps

CPACK_DEBIAN_PACKAGE_BREAKS

CPACK_DEBIAN_<COMPONENT>_PACKAGE_BREAKS
    Sets the Breaks field of the Debian package. When a binary package (P) declares that it breaks other packages (B), dpkg will not allow the package (P) which declares Breaks be unpacked unless the packages that will be broken (B) are deconfigured first. As long as the package (P) is configured, the previously deconfigured packages (B) cannot be reconfigured again.

•   Mandatory : NO

•   Default :

•   An empty string for non-component based installations

•   CPACK_DEBIAN_PACKAGE_BREAKS for component-based installations.

    See https://www.debian.org/doc/debian-policy/ch-relationships.html#s-breaks

CPACK_DEBIAN_PACKAGE_CONFLICTS

CPACK_DEBIAN_<COMPONENT>_PACKAGE_CONFLICTS
    Sets the Conflicts field of the Debian package. When one binary package declares a conflict with another using a Conflicts field, dpkg will not allow them to be unpacked on the system at the same time.

•   Mandatory : NO

•   Default :

•   An empty string for non-component based installations

•   CPACK_DEBIAN_PACKAGE_CONFLICTS for component-based installations.

    See https://www.debian.org/doc/debian-policy/ch-relationships.html#s-conflicts

    NOTE: This is a stronger restriction than Breaks, which prevents the broken package from being configured while the breaking package is in the “Unpacked” state but allows both packages to be unpacked at the same time.

CPACK_DEBIAN_PACKAGE_PROVIDES

CPACK_DEBIAN_<COMPONENT>_PACKAGE_PROVIDES
    Sets the Provides field of the Debian package. A virtual package is one which appears in the Provides control field of another package.

•   Mandatory : NO

•   Default :

•   An empty string for non-component based installations

•   CPACK_DEBIAN_PACKAGE_PROVIDES for component-based installations.

    See https://www.debian.org/doc/debian-policy/ch-relationships.html#s-virtual

CPACK_DEBIAN_PACKAGE_REPLACES

CPACK_DEBIAN_<COMPONENT>_PACKAGE_REPLACES
    Sets the Replaces field of the Debian package. Packages can declare in their control file that they should overwrite files in certain other packages, or completely replace other packages.

•   Mandatory : NO

•   Default :

•   An empty string for non-component based installations

•   CPACK_DEBIAN_PACKAGE_REPLACES for component-based installations.

    See http://www.debian.org/doc/debian-policy/ch-relationships.html#s-binarydeps

CPACK_DEBIAN_PACKAGE_RECOMMENDS

CPACK_DEBIAN_<COMPONENT>_PACKAGE_RECOMMENDS
    Sets the Recommends field of the Debian package. Allows packages to declare a strong, but not absolute, dependency on other packages.

•   Mandatory : NO

•   Default :

•   An empty string for non-component based installations

•   CPACK_DEBIAN_PACKAGE_RECOMMENDS for component-based installations.

    See http://www.debian.org/doc/debian-policy/ch-relationships.html#s-binarydeps

CPACK_DEBIAN_PACKAGE_SUGGESTS

CPACK_DEBIAN_<COMPONENT>_PACKAGE_SUGGESTS
    Sets the Suggests field of the Debian package. Allows packages to declare a suggested package install grouping.

•   Mandatory : NO

•   Default :

•   An empty string for non-component based installations

•   CPACK_DEBIAN_PACKAGE_SUGGESTS for component-based installations.

    See http://www.debian.org/doc/debian-policy/ch-relationships.html#s-binarydeps

CPACK_DEBIAN_PACKAGE_GENERATE_SHLIBS

•   Mandatory : NO

•   Default : OFF

    Allows to generate shlibs control file automatically. Compatibility is defined by CPACK_DEBIAN_PACKAGE_GENERATE_SHLIBS_POLICY variable value.

    NOTE: Libraries are only considered if they have both library name and version set. This can be done by setting SOVERSION property with set_target_properties() command.

CPACK_DEBIAN_PACKAGE_GENERATE_SHLIBS_POLICY
    Compatibility policy for auto-generated shlibs control file.

•   Mandatory : NO

•   Default : “=”

    Defines compatibility policy for auto-generated shlibs control file. Possible values: “=”, “>=”

    See https://www.debian.org/doc/debian-policy/ch-sharedlibs.html#s-sharedlibs-shlibdeps

CPACK_DEBIAN_PACKAGE_CONTROL_EXTRA

CPACK_DEBIAN_<COMPONENT>_PACKAGE_CONTROL_EXTRA
    This variable allow advanced user to add custom script to the control.tar.gz. Typical usage is for conffiles, postinst, postrm, prerm.

•   Mandatory : NO

•   Default : -

    Usage:

    set(CPACK_DEBIAN_PACKAGE_CONTROL_EXTRA
        "${CMAKE_CURRENT_SOURCE_DIR}/prerm;${CMAKE_CURRENT_SOURCE_DIR}/postrm")

    NOTE: The original permissions of the files will be used in the final package unless the variable CPACK_DEBIAN_PACKAGE_CONTROL_STRICT_PERMISSION is set. In particular, the scripts should have the proper executable flag prior to the generation of the package.

CPACK_DEBIAN_PACKAGE_CONTROL_STRICT_PERMISSION

CPACK_DEBIAN_<COMPONENT>_PACKAGE_CONTROL_STRICT_PERMISSION
    This variable indicates if the Debian policy on control files should be strictly followed.

•   Mandatory : NO

•   Default : FALSE

    Usage:

    set(CPACK_DEBIAN_PACKAGE_CONTROL_STRICT_PERMISSION TRUE)

    NOTE: This overrides the permissions on the original files, following the rules set by Debian policy https://www.debian.org/doc/debian-policy/ch-files.html#s-permissions-owners

CPACK_DEBIAN_PACKAGE_SOURCE

CPACK_DEBIAN_<COMPONENT>_PACKAGE_SOURCE
    Sets the Source field of the binary Debian package. When the binary package name is not the same as the source package name (in particular when several components/binaries are generated from one source) the source from which the binary has been generated should be indicated with the field Source.

•   Mandatory : NO

•   Default :

•   An empty string for non-component based installations

•   CPACK_DEBIAN_PACKAGE_SOURCE for component-based installations.

    See https://www.debian.org/doc/debian-policy/ch-controlfields.html#s-f-Source

    NOTE: This value is not interpreted. It is possible to pass an optional revision number of the referenced source package as well.

  Packaging of debug information

Dbgsym packages contain debug symbols for debugging packaged binaries.

Dbgsym packaging has its own set of variables:

CPACK_DEBIAN_DEBUGINFO_PACKAGE

CPACK_DEBIAN_<component>_DEBUGINFO_PACKAGE
    Enable generation of dbgsym .ddeb package(s).

•   Mandatory : NO

•   Default : OFF

    NOTE: Binaries must contain debug symbols before packaging so use either Debug or RelWithDebInfo for CMAKE_BUILD_TYPE variable value.

  Building Debian packages on Windows

To communicate UNIX file permissions from the install stage to the CPack DEB generator the “cmake_mode_t” NTFS alternate data stream (ADT) is used.

When a filesystem without ADT support is used only owner read/write permissions can be preserved.

  Reproducible packages

The environment variable SOURCE_DATE_EPOCH may be set to a UNIX timestamp, defined as the number of seconds, excluding leap seconds, since 01 Jan 1970 00:00:00 UTC. If set, the CPack DEB generator will use its value for timestamps in the package.

  CPack DragNDrop Generator

The DragNDrop CPack generator (macOS) creates a DMG image.

  Variables specific to CPack DragNDrop generator

The following variables are specific to the DragNDrop installers built on macOS:

CPACK_DMG_VOLUME_NAME
    The volume name of the generated disk image. Defaults to CPACK_PACKAGE_FILE_NAME.

CPACK_DMG_FORMAT
    The disk image format. Common values are UDRO (UDIF read-only), UDZO (UDIF zlib-compressed) or UDBZ (UDIF bzip2-compressed). Refer to hdiutil(1) for more information on other available formats. Defaults to UDZO.

CPACK_DMG_DS_STORE
    Path to a custom .DS_Store file. This .DS_Store file can be used to specify the Finder window position/geometry and layout (such as hidden toolbars, placement of the icons etc.). This file has to be generated by the Finder (either manually or through AppleScript) using a normal folder from which the .DS_Store file can then be extracted.

CPACK_DMG_DS_STORE_SETUP_SCRIPT
    Path to a custom AppleScript file. This AppleScript is used to generate a .DS_Store file which specifies the Finder window position/geometry and layout (such as hidden toolbars, placement of the icons etc.). By specifying a custom AppleScript there is no need to use CPACK_DMG_DS_STORE, as the .DS_Store that is generated by the AppleScript will be packaged.

CPACK_DMG_BACKGROUND_IMAGE
    Path to an image file to be used as the background. This file will be copied to .background/background.<ext>, where <ext> is the original image file extension. The background image is installed into the image before CPACK_DMG_DS_STORE_SETUP_SCRIPT is executed or CPACK_DMG_DS_STORE is installed. By default no background image is set.

CPACK_DMG_DISABLE_APPLICATIONS_SYMLINK
    Default behaviour is to include a symlink to /Applications in the DMG. Set this option to ON to avoid adding the symlink.

CPACK_DMG_SLA_DIR
    Directory where license and menu files for different languages are stored. Setting this causes CPack to look for a <language>.menu.txt and <language>.license.txt or <language>.license.rtf file for every language defined in CPACK_DMG_SLA_LANGUAGES. If both this variable and CPACK_RESOURCE_FILE_LICENSE are set, CPack will only look for the menu files and use the same license file for all languages. If both <language>.license.txt and <language>.license.rtf exist, the .txt file will be used.

CPACK_DMG_SLA_LANGUAGES
    Languages for which a license agreement is provided when mounting the generated DMG. A menu file consists of 9 lines of text. The first line is is the name of the language itself, uppercase, in English (e.g. German). The other lines are translations of the following strings:

•   Agree

•   Disagree

•   Print

•   Save…

•   You agree to the terms of the License Agreement when you click the “Agree” button.

•   Software License Agreement

•   This text cannot be saved. The disk may be full or locked, or the file may be locked.

•   Unable to print. Make sure you have selected a printer.

    For every language in this list, CPack will try to find files <language>.menu.txt and <language>.license.txt in the directory specified by the CPACK_DMG_SLA_DIR variable.

CPACK_DMG_<component>_FILE_NAME
    File name when packaging <component> as its own DMG (CPACK_COMPONENTS_GROUPING set to IGNORE).

•   Default: CPACK_PACKAGE_FILE_NAME-<component>

CPACK_COMMAND_HDIUTIL
    Path to the hdiutil(1) command used to operate on disk image files on macOS. This variable can be used to override the automatically detected command (or specify its location if the auto-detection fails to find it).

CPACK_COMMAND_SETFILE
    Path to the SetFile(1) command used to set extended attributes on files and directories on macOS. This variable can be used to override the automatically detected command (or specify its location if the auto-detection fails to find it).

CPACK_COMMAND_REZ
    Path to the Rez(1) command used to compile resources on macOS. This variable can be used to override the automatically detected command (or specify its location if the auto-detection fails to find it).

  CPack External Generator

CPack provides many generators to create packages for a variety of platforms and packaging systems. The intention is for CMake/CPack to be a complete end-to-end solution for building and packaging a software project. However, it may not always be possible to use CPack for the entire packaging process, due to either technical limitations or policies that require the use of certain tools. For this reason, CPack provides the “External” generator, which allows external packaging software to take advantage of some of the functionality provided by CPack, such as component installation and the dependency graph.

  Integration with External Packaging Tools

The CPack External generator generates a .json file containing the CPack internal metadata, which gives external software information on how to package the software. External packaging software may itself invoke CPack, consume the generated metadata, install and package files as required.

Alternatively CPack can invoke an external packaging software through an optional custom CMake script in CPACK_EXTERNAL_PACKAGE_SCRIPT instead.

Staging of installation files may also optionally be taken care of by the generator when enabled through the CPACK_EXTERNAL_ENABLE_STAGING variable.

  JSON Format

The JSON metadata file contains a list of CPack components and component groups, the various options passed to cpack_add_component() and cpack_add_component_group(), the dependencies between the components and component groups, and various other options passed to CPack.

The JSON’s root object will always provide two fields: formatVersionMajor and formatVersionMinor, which are always integers that describe the output format of the generator. Backwards-compatible changes to the output format (for example, adding a new field that didn’t exist before) cause the minor version to be incremented, and backwards-incompatible changes (for example, deleting a field or changing its meaning) cause the major version to be incremented and the minor version reset to 0. The format version is always of the format major.minor. In other words, it always has exactly two parts, separated by a period.

You can request one or more specific versions of the output format as described below with CPACK_EXTERNAL_REQUESTED_VERSIONS. The output format will have a major version that exactly matches the requested major version, and a minor version that is greater than or equal to the requested minor version. If no version is requested with CPACK_EXTERNAL_REQUESTED_VERSIONS, the latest known major version is used by default. Currently, the only supported format is 1.0, which is described below.

  Version 1.0

In addition to the standard format fields, format version 1.0 provides the following fields in the root:

components
    The components field is an object with component names as the keys and objects describing the components as the values. The component objects have the following fields:

name
    The name of the component. This is always the same as the key in the components object.

displayName
    The value of the DISPLAY_NAME field passed to cpack_add_component().

description
    The value of the DESCRIPTION field passed to cpack_add_component().

isHidden
    True if HIDDEN was passed to cpack_add_component(), false if it was not.

isRequired
    True if REQUIRED was passed to cpack_add_component(), false if it was not.

isDisabledByDefault
    True if DISABLED was passed to cpack_add_component(), false if it was not.

group
    Only present if GROUP was passed to cpack_add_component(). If so, this field is a string value containing the component’s group.

dependencies
    An array of components the component depends on. This contains the values in the DEPENDS argument passed to cpack_add_component(). If no DEPENDS argument was passed, this is an empty list.

installationTypes
    An array of installation types the component is part of. This contains the values in the INSTALL_TYPES argument passed to cpack_add_component(). If no INSTALL_TYPES argument was passed, this is an empty list.

isDownloaded
    True if DOWNLOADED was passed to cpack_add_component(), false if it was not.

archiveFile
    The name of the archive file passed with the ARCHIVE_FILE argument to cpack_add_component(). If no ARCHIVE_FILE argument was passed, this is an empty string.

  Variables specific to CPack External generator

CPACK_EXTERNAL_REQUESTED_VERSIONS
    This variable is used to request a specific version of the CPack External generator. It is a list of major.minor values, separated by semicolons.

    If this variable is set to a non-empty value, the CPack External generator will iterate through each item in the list to search for a version that it knows how to generate. Requested versions should be listed in order of descending preference by the client software, as the first matching version in the list will be generated.

    The generator knows how to generate the version if it has a versioned generator whose major version exactly matches the requested major version, and whose minor version is greater than or equal to the requested minor version. For example, if CPACK_EXTERNAL_REQUESTED_VERSIONS contains 1.0, and the CPack External generator knows how to generate 1.1, it will generate 1.1. If the generator doesn’t know how to generate a version in the list, it skips the version and looks at the next one. If it doesn’t know how to generate any of the requested versions, an error is thrown.

    If this variable is not set, or is empty, the CPack External generator will generate the highest major and minor version that it knows how to generate.

    If an invalid version is encountered in CPACK_EXTERNAL_REQUESTED_VERSIONS (one that doesn’t match major.minor, where major and minor are integers), it is ignored.

CPACK_EXTERNAL_ENABLE_STAGING
    This variable can be set to true to enable optional installation into a temporary staging area which can then be picked up and packaged by an external packaging tool. The top level directory used by CPack for the current packaging task is contained in CPACK_TOPLEVEL_DIRECTORY. It is automatically cleaned up on each run before packaging is initiated and can be used for custom temporary files required by the external packaging tool. It also contains the staging area CPACK_TEMPORARY_DIRECTORY into which CPack performs the installation when staging is enabled.

CPACK_EXTERNAL_PACKAGE_SCRIPT
    This variable can optionally specify the full path to a CMake script file to be run as part of the CPack invocation. It is invoked after (optional) staging took place and may run an external packaging tool. The script has access to the variables defined by the CPack config file.

CPACK_EXTERNAL_BUILT_PACKAGES
    The CPACK_EXTERNAL_PACKAGE_SCRIPT script may set this list variable to the full paths of generated package files. CPack will copy these files from the staging directory back to the top build directory and possibly produce checksum files if the CPACK_PACKAGE_CHECKSUM is set.

  CPack FreeBSD Generator

The built in (binary) CPack FreeBSD (pkg) generator (Unix only)

  Variables affecting the CPack FreeBSD (pkg) generator

•   CPACK_ARCHIVE_THREADS

  Variables specific to CPack FreeBSD (pkg) generator

The CPack FreeBSD generator may be used to create pkg(8) packages – these may be used on FreeBSD, DragonflyBSD, NetBSD, OpenBSD, but also on Linux or OSX, depending on the installed package-management tools – using CPack.

The CPack FreeBSD generator is a CPack generator and uses the CPACK_XXX variables used by CPack. It tries to re-use packaging information that may already be specified for Debian packages for the CPack DEB Generator. It also tries to re-use RPM packaging information when Debian does not specify.

The CPack FreeBSD generator should work on any host with libpkg installed. The packages it produces are specific to the host architecture and ABI.

The CPack FreeBSD generator sets package-metadata through CPACK_FREEBSD_XXX variables. The CPack FreeBSD generator, unlike the CPack Deb generator, does not specially support componentized packages; a single package is created from all the software artifacts created through CMake.

All of the variables can be set specifically for FreeBSD packaging in the CPackConfig file or in CMakeLists.txt, but most of them have defaults that use general settings (e.g. CMAKE_PROJECT_NAME) or Debian-specific variables when those make sense (e.g. the homepage of an upstream project is usually unchanged by the flavor of packaging). When there is no Debian information to fall back on, but the RPM packaging has it, fall back to the RPM information (e.g. package license).

CPACK_FREEBSD_PACKAGE_NAME
    Sets the package name (in the package manifest, but also affects the output filename).

•   Mandatory: YES

•   Default:

•   CPACK_PACKAGE_NAME (this is always set by CPack itself, based on CMAKE_PROJECT_NAME).

CPACK_FREEBSD_PACKAGE_COMMENT
    Sets the package comment. This is the short description displayed by pkg(8) in standard “pkg info” output.

•   Mandatory: YES

•   Default:

•   CPACK_PACKAGE_DESCRIPTION_SUMMARY (this is always set by CPack itself, if nothing else sets it explicitly).

•   PROJECT_DESCRIPTION (this can be set with the DESCRIPTION parameter for project()).

CPACK_FREEBSD_PACKAGE_DESCRIPTION
    Sets the package description. This is the long description of the package, given by “pkg info” with a specific package as argument.

•   Mandatory: YES

•   Default:

•   CPACK_DEBIAN_PACKAGE_DESCRIPTION (this may be set already for Debian packaging, so we may as well re-use it).

CPACK_FREEBSD_PACKAGE_WWW
    The URL of the web site for this package, preferably (when applicable) the site from which the original source can be obtained and any additional upstream documentation or information may be found.

•   Mandatory: YES

•   Default:

•   CMAKE_PROJECT_HOMEPAGE_URL, or if that is not set, CPACK_DEBIAN_PACKAGE_HOMEPAGE (this may be set already for Debian packaging, so we may as well re-use it).

CPACK_FREEBSD_PACKAGE_LICENSE
    The license, or licenses, which apply to this software package. This must be one or more license-identifiers that pkg recognizes as acceptable license identifiers (e.g. “GPLv2”).

•   Mandatory: YES

•   Default:

•   CPACK_RPM_PACKAGE_LICENSE

CPACK_FREEBSD_PACKAGE_LICENSE_LOGIC
    This variable is only of importance if there is more than one license. The default is “single”, which is only applicable to a single license. Other acceptable values are determined by pkg – those are “dual” or “multi” – meaning choice (OR) or simultaneous (AND) application of the licenses.

•   Mandatory: NO

•   Default: single

CPACK_FREEBSD_PACKAGE_MAINTAINER
    The FreeBSD maintainer (e.g. kde@freebsd.org) of this package.

•   Mandatory: YES

•   Default: none

CPACK_FREEBSD_PACKAGE_ORIGIN
    The origin (ports label) of this package; for packages built by CPack outside of the ports system this is of less importance. The default puts the package somewhere under misc/, as a stopgap.

•   Mandatory: YES

•   Default: misc/<package name>

CPACK_FREEBSD_PACKAGE_CATEGORIES
    The ports categories where this package lives (if it were to be built from ports). If none is set a single category is determined based on the package origin.

•   Mandatory: YES

•   Default: derived from ORIGIN

CPACK_FREEBSD_PACKAGE_DEPS
    A list of package origins that should be added as package dependencies. These are in the form <category>/<packagename>, e.g. x11/libkonq. No version information needs to be provided (this is not included in the manifest).

•   Mandatory: NO

•   Default: empty

  CPack IFW Generator

Configure and run the Qt Installer Framework to generate a Qt installer.

  Overview

This cpack generator generates configuration and meta information for the Qt Installer Framework (QtIFW), and runs QtIFW tools to generate a Qt installer.

QtIFW provides tools and utilities to create installers for the platforms supported by Qt: Linux, Microsoft Windows, and macOS.

To make use of this generator, QtIFW needs to be installed. The CPackIFW module looks for the location of the QtIFW command-line utilities, and defines several commands to control the behavior of this generator.

  Variables

You can use the following variables to change behavior of CPack IFW generator.

    The path to installerbase.

CPACK_IFW_DEVTOOL_EXECUTABLE
    The path to devtool.

  Hints for Finding QtIFW

Generally, the CPack IFW generator automatically finds QtIFW tools, but if you don’t use a default path for installation of the QtIFW tools, the path may be specified in either a CMake or an environment variable:

CPACK_IFW_ROOT
    An CMake variable which specifies the location of the QtIFW tool suite.

    The variable will be cached in the CPackConfig.cmake file and used at CPack runtime.

QTIFWDIR
    An environment variable which specifies the location of the QtIFW tool suite.

    NOTE: The specified path should not contain “bin” at the end (for example: “D:\DevTools\QtIFW2.0.5”).

    The CPACK_IFW_ROOT variable has a higher priority and overrides the value of the QTIFWDIR variable.

  Other Settings

  Online installer

By default, this generator generates an offline installer. This means that that all packaged files are fully contained in the installer executable.

In contrast, an online installer will download some or all components from a remote server.

The DOWNLOADED option in the cpack_add_component() command specifies that a component is to be downloaded. Alternatively, the ALL option in the cpack_configure_downloads() command specifies that all components are to be be downloaded.

The cpack_ifw_add_repository() command and the CPACK_IFW_DOWNLOAD_ALL variable allow for more specific configuration.

When there are online components, CPack will write them to archive files. The help page of the CPackComponent module, especially the section on the cpack_configure_downloads() function, explains how to make these files accessible from a download URL.

  Internationalization

Some variables and command arguments support internationalization via CMake script. This is an optional feature.

Installers created by QtIFW tools have built-in support for internationalization and many phrases are localized to many languages, but this does not apply to the description of the your components and groups that will be distributed.

Localization of the description of your components and groups is useful for users of your installers.

A localized variable or argument can contain a single default value, and a set of pairs the name of the locale and the localized value.

For example:

set(LOCALIZABLE_VARIABLE "Default value"
  en "English value"
  en_US "American value"
  en_GB "Great Britain value"
  )

  CPack NuGet Generator

When build a NuGet package there is no direct way to control an output filename due a lack of the corresponding CLI option of NuGet, so there is no CPACK_NUGET_PACKAGE_FILENAME variable. To form the output filename NuGet uses the package name and the version according to its built-in rules.

Also, be aware that including a top level directory (CPACK_INCLUDE_TOPLEVEL_DIRECTORY) is ignored by this generator.

  Variables specific to CPack NuGet generator

The CPack NuGet generator may be used to create NuGet packages using CPack. The CPack NuGet generator is a CPack generator thus it uses the CPACK_XXX variables used by CPack.

The CPack NuGet generator has specific features which are controlled by the specifics CPACK_NUGET_XXX variables. In the “one per group” mode (see CPACK_COMPONENTS_GROUPING), <compName> placeholder in the variables below would contain a group name (uppercased and turned into a “C” identifier).

PackageMaker CPack generator (macOS).

Deprecated since version 3.17: Xcode no longer distributes the PackageMaker tools. This CPack generator will be removed in a future version of CPack.

  Variables specific to CPack PackageMaker generator

The following variable is specific to installers built on Mac macOS using PackageMaker:

CPACK_OSX_PACKAGE_VERSION
    The version of macOS that the resulting PackageMaker archive should be compatible with. Different versions of macOS support different features. For example, CPack can only build component-based installers for macOS 10.4 or newer, and can only build installers that download components on-the-fly for macOS 10.5 or newer. If left blank, this value will be set to the minimum version of macOS that supports the requested features. Set this variable to some value (e.g., 10.4) only if you want to guarantee that your installer will work on that version of macOS, and don’t mind missing extra features available in the installer shipping with later versions of macOS.

CPACK_PACKAGEMAKER_BACKGROUND
    Adds a background to Distribution XML if specified. The value contains the path to image in Resources directory.

CPACK_PACKAGEMAKER_BACKGROUND_ALIGNMENT
    Adds an alignment attribute to the background in Distribution XML. Refer to Apple documentation for valid values.

CPACK_PACKAGEMAKER_BACKGROUND_SCALING
    Adds a scaling attribute to the background in Distribution XML. Refer to Apple documentation for valid values.

CPACK_PACKAGEMAKER_BACKGROUND_MIME_TYPE
    Adds a mime-type attribute to the background in Distribution XML. The option contains MIME type of an image.

  CPack RPM Generator

The built in (binary) CPack RPM generator (Unix only)

  Variables specific to CPack RPM generator

The CPack RPM generator may be used to create RPM packages using CPack. The CPack RPM generator is a CPack generator thus it uses the CPACK_XXX variables used by CPack.

The CPack RPM generator has specific features which are controlled by the specifics CPACK_RPM_XXX variables.

CPACK_RPM_<COMPONENT>_XXXX variables may be used in order to have component specific values. Note however that <COMPONENT> refers to the grouping name written in upper case. It may be either a component name or a component GROUP name. Usually those variables correspond to RPM spec file entities. One may find information about spec files here http://www.rpm.org/wiki/Docs

NOTE: <COMPONENT> part of variables is preferred to be in upper case (e.g. if component is named foo then use CPACK_RPM_FOO_XXXX variable name format) as is with other CPACK_<COMPONENT>_XXXX variables. For the purposes of back compatibility (CMake/CPack version 3.5 and lower) support for same cased component (e.g. fOo would be used as CPACK_RPM_fOo_XXXX) is still supported for variables defined in older versions of CMake/CPack but is not guaranteed for variables that will be added in the future. For the sake of back compatibility same cased component variables also override upper cased versions where both are present.

Here are some CPack RPM generator wiki resources that are here for historic reasons and are no longer maintained but may still prove useful:

•   https://gitlab.kitware.com/cmake/community/-/wikis/doc/cpack/Configuration

•   https://gitlab.kitware.com/cmake/community/-/wikis/doc/cpack/PackageGenerators#rpm-unix-only

    List of CPack RPM generator specific variables:

CPACK_RPM_COMPONENT_INSTALL
    Enable component packaging for CPack RPM generator

•   Mandatory : NO

•   Default : OFF

    If enabled (ON) multiple packages are generated. By default a single package containing files of all components is generated.

CPACK_RPM_PACKAGE_SUMMARY

CPACK_RPM_<component>_PACKAGE_SUMMARY
    The RPM package summary.

•   Mandatory : YES

•   Default : CPACK_PACKAGE_DESCRIPTION_SUMMARY

CPACK_RPM_PACKAGE_NAME

CPACK_RPM_<component>_PACKAGE_NAME
    The RPM package name.

•   Mandatory : YES

•   Default : CPACK_PACKAGE_NAME

CPACK_RPM_FILE_NAME

    Package file name.

•   Mandatory : YES

•

Default
    <CPACK_PACKAGE_FILE_NAME>[-<component>].rpm with spaces replaced by ‘-‘

    This may be set to RPM-DEFAULT to allow rpmbuild tool to generate package file name by itself. Alternatively provided package file name must end with .rpm suffix.

    NOTE: By using user provided spec file, rpm macro extensions such as for generating debuginfo packages or by simply using multiple components more than one rpm file may be generated, either from a single spec file or from multiple spec files (each component execution produces its own spec file). In such cases duplicate file names may occur as a result of this variable setting or spec file content structure. Duplicate files get overwritten and it is up to the packager to set the variables in a manner that will prevent such errors.

CPACK_RPM_MAIN_COMPONENT
    Main component that is packaged without component suffix.

•   Mandatory : NO

•   Default : -

    This variable can be set to any component or group name so that component or group rpm package is generated without component suffix in filename and package name.

CPACK_RPM_PACKAGE_EPOCH
    The RPM package epoch

•   Mandatory : No

•   Default : -

    Optional number that should be incremented when changing versioning schemas or fixing mistakes in the version numbers of older packages.

    This may be set to noarch if you know you are building a noarch package.

CPACK_RPM_PACKAGE_RELEASE
    The RPM package release.

•   Mandatory : YES

•   Default : 1

    This is the numbering of the RPM package itself, i.e. the version of the packaging and not the version of the content (see CPACK_RPM_PACKAGE_VERSION). One may change the default value if the previous packaging was buggy and/or you want to put here a fancy Linux distro specific numbering.

    NOTE: This is the string that goes into the RPM Release: field. Some distros (e.g. Fedora, CentOS) require 1%{?dist} format and not just a number. %{?dist} part can be added by setting CPACK_RPM_PACKAGE_RELEASE_DIST.

CPACK_RPM_PACKAGE_RELEASE_DIST
    The dist tag that is added RPM Release: field.

•   Mandatory : NO

•   Default : OFF

    This is the reported %{dist} tag from the current distribution or empty %{dist} if RPM macro is not set. If this variable is set then RPM Release: field value is set to ${CPACK_RPM_PACKAGE_RELEASE}%{?dist}.

CPACK_RPM_COMPRESSION_TYPE
    RPM compression type.

•   Mandatory : NO

•   Default : -

    May be used to override RPM compression type to be used to build the RPM. For example some Linux distribution now default to lzma or xz compression whereas older cannot use such RPM. Using this one can enforce compression type to be used.

    Possible values are:

•   lzma

•   xz

•   bzip2

•   gzip

CPACK_RPM_PACKAGE_RELOCATABLE
    build a relocatable RPM.

•   Mandatory : NO

•   Default : CPACK_PACKAGE_RELOCATABLE

    If this variable is set to TRUE or ON, the CPack RPM generator will try to build a relocatable RPM package. A relocatable RPM may be installed using:

    rpm --prefix or --relocate

    in order to install it at an alternate place see rpm(8). Note that currently this may fail if CPACK_SET_DESTDIR is set to ON. If CPACK_SET_DESTDIR is set then you will get a warning message but if there is file installed with absolute path you’ll get unexpected behavior.

CPACK_RPM_SPEC_INSTALL_POST
    Deprecated - use CPACK_RPM_SPEC_MORE_DEFINE instead.

•   Mandatory : NO

•   Default : -

•   Deprecated: YES

CPACK_RPM_SPEC_MORE_DEFINE
    RPM extended spec definitions lines.

•   Mandatory : NO

•   Default : -

    May be used to add any %define lines to the generated spec file. An example of its use is to prevent stripping of executables (but note that this may also disable other default post install processing):

CPACK_RPM_USER_BINARY_SPECFILE

CPACK_RPM_<componentName>_USER_BINARY_SPECFILE
    A user provided spec file.

•   Mandatory : NO

•   Default : -

    May be set by the user in order to specify a USER binary spec file to be used by the CPack RPM generator instead of generating the file. The specified file will be processed by configure_file( @ONLY).

CPACK_RPM_GENERATE_USER_BINARY_SPECFILE_TEMPLATE
    Spec file template.

•   Mandatory : NO

•   Default : -

    If set CPack will generate a template for USER specified binary spec file and stop with an error. For example launch CPack like this:

    cpack -D CPACK_RPM_GENERATE_USER_BINARY_SPECFILE_TEMPLATE=1 -G RPM

    The user may then use this file in order to hand-craft is own binary spec file which may be used with CPACK_RPM_USER_BINARY_SPECFILE.

CPACK_RPM_PRE_INSTALL_SCRIPT_FILE

CPACK_RPM_PRE_UNINSTALL_SCRIPT_FILE

CPACK_RPM_PRE_TRANS_SCRIPT_FILE
    Path to file containing pre install/uninstall/transaction script.

•   Mandatory : NO

•   Default : -

    May be used to embed a pre installation/uninstallation/transaction script in the spec file. The referred script file (or both) will be read and directly put after the %pre or %preun section If CPACK_RPM_COMPONENT_INSTALL is set to ON the install/uninstall/transaction script for each component can be overridden with CPACK_RPM_<COMPONENT>_PRE_INSTALL_SCRIPT_FILE, CPACK_RPM_<COMPONENT>_PRE_UNINSTALL_SCRIPT_FILE, and CPACK_RPM_<COMPONENT>_PRE_TRANS_SCRIPT_FILE One may verify which scriptlet has been included with:

    rpm -qp --scripts  package.rpm

CPACK_RPM_POST_INSTALL_SCRIPT_FILE

CPACK_RPM_POST_UNINSTALL_SCRIPT_FILE

CPACK_RPM_POST_TRANS_SCRIPT_FILE
    Path to file containing post install/uninstall/transaction script.

•   Mandatory : NO

•   Default : -

    May be used to embed a post installation/uninstallation/transaction script in the spec file. The referred script file (or both) will be read and directly put after the %post or %postun section. If CPACK_RPM_COMPONENT_INSTALL is set to ON the install/uninstall/transaction script for each component can be overridden with CPACK_RPM_<COMPONENT>_POST_INSTALL_SCRIPT_FILE, CPACK_RPM_<COMPONENT>_POST_UNINSTALL_SCRIPT_FILE, and CPACK_RPM_<COMPONENT>_POST_TRANS_SCRIPT_FILE One may verify which scriptlet has been included with:

    rpm -qp --scripts  package.rpm

CPACK_RPM_USER_FILELIST

CPACK_RPM_<COMPONENT>_USER_FILELIST

•   Mandatory : NO

•   Default : -

    May be used to explicitly specify %(<directive>) file line in the spec file. Like %config(noreplace) or any other directive that be found in the %files section. You can have multiple directives per line, as in %attr(600,root,root) %config(noreplace). Since the CPack RPM generator is generating the list of files (and directories) the user specified files of the CPACK_RPM_<COMPONENT>_USER_FILELIST list will be removed from the generated list. If referring to directories do not add a trailing slash.

CPACK_RPM_CHANGELOG_FILE
    RPM changelog file.

•   Mandatory : NO

•   Default : -

    May be used to embed a changelog in the spec file. The referred file will be read and directly put after the %changelog section.

CPACK_RPM_EXCLUDE_FROM_AUTO_FILELIST
    list of path to be excluded.

•   Mandatory : NO

•

Default
    /etc /etc/init.d /usr /usr/bin /usr/include /usr/lib /usr/libx32 /usr/lib64 /usr/share /usr/share/aclocal /usr/share/doc

    May be used to exclude path (directories or files) from the auto-generated list of paths discovered by CPack RPM. The default value contains a reasonable set of values if the variable is not defined by the user. If the variable is defined by the user then the CPack RPM generator will NOT any of the default path. If you want to add some path to the default list then you can use CPACK_RPM_EXCLUDE_FROM_AUTO_FILELIST_ADDITION variable.

CPACK_RPM_EXCLUDE_FROM_AUTO_FILELIST_ADDITION
    additional list of path to be excluded.

•   Mandatory : NO

•   Default : -

    May be used to add more exclude path (directories or files) from the initial default list of excluded paths. See CPACK_RPM_EXCLUDE_FROM_AUTO_FILELIST.

CPACK_RPM_RELOCATION_PATHS
    Packages relocation paths list.

•   Mandatory : NO

•   Default : -

    May be used to specify more than one relocation path per relocatable RPM. Variable contains a list of relocation paths that if relative are prefixed by the value of CPACK_RPM_<COMPONENT>_PACKAGE_PREFIX or by the value of CPACK_PACKAGING_INSTALL_PREFIX if the component version is not provided. Variable is not component based as its content can be used to set a different path prefix for e.g. binary dir and documentation dir at the same time. Only prefixes that are required by a certain component are added to that component - component must contain at least one file/directory/symbolic link with CPACK_RPM_RELOCATION_PATHS prefix for a certain relocation path to be added. Package will not contain any relocation paths if there are no files/directories/symbolic links on any of the provided prefix locations. Packages that either do not contain any relocation paths or contain files/directories/symbolic links that are outside relocation paths print out an AUTHOR_WARNING that RPM will be partially relocatable.

CPACK_RPM_<COMPONENT>_PACKAGE_PREFIX
    Per component relocation path install prefix.

•   Mandatory : NO

•   Default : CPACK_PACKAGING_INSTALL_PREFIX

    May be used to set per component CPACK_PACKAGING_INSTALL_PREFIX for relocatable RPM packages.

CPACK_RPM_NO_INSTALL_PREFIX_RELOCATION

CPACK_RPM_NO_<COMPONENT>_INSTALL_PREFIX_RELOCATION
    Removal of default install prefix from relocation paths list.

•   Mandatory : NO

•

Default
    CPACK_PACKAGING_INSTALL_PREFIX or CPACK_RPM_<COMPONENT>_PACKAGE_PREFIX are treated as one of relocation paths

    May be used to remove CPACK_PACKAGING_INSTALL_PREFIX and CPACK_RPM_<COMPONENT>_PACKAGE_PREFIX from relocatable RPM prefix paths.

CPACK_RPM_ADDITIONAL_MAN_DIRS

•   Mandatory : NO

•   Default : -

    May be used to set additional man dirs that could potentially be compressed by brp-compress RPM macro. Variable content must be a list of regular expressions that point to directories containing man files or to man files directly. Note that in order to compress man pages a path must also be present in brp-compress RPM script and that brp-compress script must be added to RPM configuration by the operating system.

    Regular expressions that are added by default were taken from brp-compress RPM macro:

•   /usr/man/man.*

•   /usr/man/.*/man.*

•   /usr/info.*

•   /usr/share/man/man.*

•   /usr/share/man/.*/man.*

•   /usr/share/info.*

•   /usr/kerberos/man.*

•   /usr/X11R6/man/man.*

•   /usr/lib/perl5/man/man.*

•   /usr/share/doc/.*/man/man.*

•   /usr/lib/.*/man/man.*

CPACK_RPM_DEFAULT_USER

CPACK_RPM_<compName>_DEFAULT_USER
    default user ownership of RPM content

•   Mandatory : NO

•   Default : root

    Value should be user name and not UID. Note that <compName> must be in upper-case.

CPACK_RPM_DEFAULT_GROUP

CPACK_RPM_<compName>_DEFAULT_GROUP
    default group ownership of RPM content

•   Mandatory : NO

•   Default : root

    Value should be group name and not GID. Note that <compName> must be in upper-case.

CPACK_RPM_DEFAULT_FILE_PERMISSIONS

CPACK_RPM_<compName>_DEFAULT_FILE_PERMISSIONS
    default permissions used for packaged files

•   Mandatory : NO

•   Default : - (system default)

    Accepted values are lists with PERMISSIONS. Valid permissions are:

•   OWNER_READ

•   OWNER_WRITE

•   OWNER_EXECUTE

•   GROUP_READ

•   GROUP_WRITE

•   GROUP_EXECUTE

•   WORLD_READ

•   WORLD_WRITE

•   WORLD_EXECUTE

    Note that <compName> must be in upper-case.

CPACK_RPM_DEFAULT_DIR_PERMISSIONS

CPACK_RPM_<compName>_DEFAULT_DIR_PERMISSIONS
    default permissions used for packaged directories

•   Mandatory : NO

•   Default : - (system default)

    Accepted values are lists with PERMISSIONS. Valid permissions are the same as for CPACK_RPM_DEFAULT_FILE_PERMISSIONS. Note that <compName> must be in upper-case.

CPACK_RPM_INSTALL_WITH_EXEC
    force execute permissions on programs and shared libraries

•   Mandatory : NO

•   Default : - (system default)

    Force set owner, group and world execute permissions on programs and shared libraries. This can be used for creating valid rpm packages on systems such as Debian where shared libraries do not have execute permissions set.

    NOTE: Programs and shared libraries without execute permissions are ignored during separation of debug symbols from the binary for debuginfo packages.

  Packaging of Symbolic Links

The CPack RPM generator supports packaging of symbolic links:

execute_process(COMMAND ${CMAKE_COMMAND}
  -E create_symlink <relative_path_location> <symlink_name>)
install(FILES ${CMAKE_CURRENT_BINARY_DIR}/<symlink_name>
  DESTINATION <symlink_location> COMPONENT libraries)

Symbolic links will be optimized (paths will be shortened if possible) before being added to the package or if multiple relocation paths are detected, a post install symlink relocation script will be generated.

Symbolic links may point to locations that are not packaged by the same package (either a different component or even not packaged at all) but those locations will be treated as if they were a part of the package while determining if symlink should be either created or present in a post install script - depending on relocation paths.

Symbolic links that point to locations outside packaging path produce a warning and are treated as non relocatable permanent symbolic links.

Currently there are a few limitations though:

•   For component based packaging component interdependency is not checked when processing symbolic links. Symbolic links pointing to content of a different component are treated the same way as if pointing to location that will not be packaged.

•   Symbolic links pointing to a location through one or more intermediate symbolic links will not be handled differently - if the intermediate symbolic link(s) is also on a relocatable path, relocating it during package installation may cause initial symbolic link to point to an invalid location.

  Packaging of debug information

Debuginfo packages contain debug symbols and sources for debugging packaged binaries.

Debuginfo RPM packaging has its own set of variables:

CPACK_RPM_DEBUGINFO_PACKAGE

CPACK_RPM_<component>_DEBUGINFO_PACKAGE
    Enable generation of debuginfo RPM package(s).

•   Mandatory : NO

•   Default : OFF

    NOTE: Binaries must contain debug symbols before packaging so use either Debug or RelWithDebInfo for CMAKE_BUILD_TYPE variable value.

    NOTE: Packages generated from packages without binary files, with binary files but without execute permissions or without debug symbols will cause packaging termination.

CPACK_BUILD_SOURCE_DIRS
    Provides locations of root directories of source files from which binaries were built.

•   Mandatory : YES if CPACK_RPM_DEBUGINFO_PACKAGE is set

•   Default : -

    NOTE: For CMake project CPACK_BUILD_SOURCE_DIRS is set by default to point to CMAKE_SOURCE_DIR and CMAKE_BINARY_DIR paths.

    NOTE: Sources with path prefixes that do not fall under any location provided with CPACK_BUILD_SOURCE_DIRS will not be present in debuginfo package.

CPACK_RPM_BUILD_SOURCE_DIRS_PREFIX

CPACK_RPM_<component>_BUILD_SOURCE_DIRS_PREFIX
    Prefix of location where sources will be placed during package installation.

•   Mandatory : YES if CPACK_RPM_DEBUGINFO_PACKAGE is set

•

Default
    “/usr/src/debug/<CPACK_PACKAGE_FILE_NAME>” and for component packaging “/usr/src/debug/<CPACK_PACKAGE_FILE_NAME>-<component>”

    NOTE: Each source path prefix is additionally suffixed by src_<index> where index is index of the path used from CPACK_BUILD_SOURCE_DIRS variable. This produces <CPACK_RPM_BUILD_SOURCE_DIRS_PREFIX>/src_<index> replacement path. Limitation is that replaced path part must be shorter or of equal length than the length of its replacement. If that is not the case either CPACK_RPM_BUILD_SOURCE_DIRS_PREFIX variable has to be set to a shorter path or source directories must be placed on a longer path.

CPACK_RPM_DEBUGINFO_EXCLUDE_DIRS
    Directories containing sources that should be excluded from debuginfo packages.

•   Mandatory : NO

•   Default : “/usr /usr/src /usr/src/debug”

    Listed paths are owned by other RPM packages and should therefore not be deleted on debuginfo package uninstallation.

CPACK_RPM_DEBUGINFO_EXCLUDE_DIRS_ADDITION
    Paths that should be appended to CPACK_RPM_DEBUGINFO_EXCLUDE_DIRS for exclusion.

•   Mandatory : NO

•   Default : -

CPACK_RPM_DEBUGINFO_SINGLE_PACKAGE
    Create a single debuginfo package even if components packaging is set.

•   Mandatory : NO

•   Default : OFF

    When this variable is enabled it produces a single debuginfo package even if component packaging is enabled.

    When using this feature in combination with components packaging and there is more than one component this variable requires CPACK_RPM_MAIN_COMPONENT to be set.

    NOTE: If none of the CPACK_RPM_<component>_DEBUGINFO_PACKAGE variables is set then CPACK_RPM_DEBUGINFO_PACKAGE is automatically set to ON when CPACK_RPM_DEBUGINFO_SINGLE_PACKAGE is set.

CPACK_RPM_DEBUGINFO_FILE_NAME

CPACK_RPM_<component>_DEBUGINFO_FILE_NAME
    Debuginfo package file name.

•   Mandatory : NO

•   Default : rpmbuild tool generated package file name

    Alternatively provided debuginfo package file name must end with .rpm suffix and should differ from file names of other generated packages.

    Variable may contain @cpack_component@ placeholder which will be replaced by component name if component packaging is enabled otherwise it deletes the placeholder.

    Setting the variable to RPM-DEFAULT may be used to explicitly set filename generation to default.

    NOTE: CPACK_RPM_FILE_NAME also supports rpmbuild tool generated package file name - disabled by default but can be enabled by setting the variable to RPM-DEFAULT.

  Packaging of sources (SRPM)

SRPM packaging is enabled by setting CPACK_RPM_PACKAGE_SOURCES variable while usually using CPACK_INSTALLED_DIRECTORIES variable to provide directory containing CMakeLists.txt and source files.

For CMake projects SRPM package would be produced by executing:

cpack -G RPM --config ./CPackSourceConfig.cmake

NOTE: Produced SRPM package is expected to be built with cmake(1) executable and packaged with cpack(1) executable so CMakeLists.txt has to be located in root source directory and must be able to generate binary rpm packages by executing cpack -G command. The two executables as well as rpmbuild must also be present when generating binary rpm packages from the produced SRPM package.

Once the SRPM package is generated it can be used to generate binary packages by creating a directory structure for rpm generation and executing rpmbuild tool:

mkdir -p build_dir/{BUILD,BUILDROOT,RPMS,SOURCES,SPECS,SRPMS}
rpmbuild --define "_topdir <path_to_build_dir>" --rebuild <SRPM_file_name>

Generated packages will be located in build_dir/RPMS directory or its sub directories.

NOTE: SRPM package internally uses CPack/RPM generator to generate binary packages so CMakeScripts.txt can decide during the SRPM to binary rpm generation step what content the package(s) should have as well as how they should be packaged (monolithic or components). CMake can decide this for e.g. by reading environment variables set by the package manager before starting the process of generating binary rpm packages. This way a single SRPM package can be used to produce different binary rpm packages on different platforms depending on the platform’s packaging rules.

Source RPM packaging has its own set of variables:

CPACK_RPM_PACKAGE_SOURCES
    Should the content be packaged as a source rpm (default is binary rpm).

•   Mandatory : NO

•   Default : OFF

    NOTE: For cmake projects CPACK_RPM_PACKAGE_SOURCES variable is set to OFF in CPackConfig.cmake and ON in CPackSourceConfig.cmake generated files.

CPACK_RPM_SOURCE_PKG_BUILD_PARAMS
    Additional command-line parameters provided to cmake(1) executable.

•   Mandatory : NO

•   Default : -

CPACK_RPM_SOURCE_PKG_PACKAGING_INSTALL_PREFIX
    Packaging install prefix that would be provided in CPACK_PACKAGING_INSTALL_PREFIX variable for producing binary RPM packages.

•   Mandatory : YES

•   Default : “/”

CPACK_RPM_BUILDREQUIRES
    List of source rpm build dependencies.

•   Mandatory : NO

•   Default : -

    May be used to set source RPM build dependencies (BuildRequires). Note that you must enclose the complete build requirements string between quotes, for example:

    set(CPACK_RPM_BUILDREQUIRES "python >= 2.5.0, cmake >= 2.8")

  CPack WIX Generator

CPack WIX generator specific options

  Variables specific to CPack WIX generator

The following variables are specific to the installers built on Windows using WiX.

CPACK_WIX_UPGRADE_GUID
    Upgrade GUID (Product/@UpgradeCode)

    Will be automatically generated unless explicitly provided.

    It should be explicitly set to a constant generated globally unique identifier (GUID) to allow your installers to replace existing installations that use the same GUID.

    You may for example explicitly set this variable in your CMakeLists.txt to the value that has been generated per default. You should not use GUIDs that you did not generate yourself or which may belong to other projects.

    A GUID shall have the following fixed length syntax:

    XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX

    (each X represents an uppercase hexadecimal digit)

CPACK_WIX_PRODUCT_GUID
    Product GUID (Product/@Id)

    Will be automatically generated unless explicitly provided.

    If explicitly provided this will set the Product Id of your installer.

    The installer will abort if it detects a pre-existing installation that uses the same GUID.

    The GUID shall use the syntax described for CPACK_WIX_UPGRADE_GUID.

CPACK_WIX_LICENSE_RTF
    RTF License File

    If CPACK_RESOURCE_FILE_LICENSE has an .rtf extension it is used as-is.

    If CPACK_RESOURCE_FILE_LICENSE has an .txt extension it is implicitly converted to RTF by the WIX Generator. The expected encoding of the .txt file is UTF-8.

    With CPACK_WIX_LICENSE_RTF you can override the license file used by the WIX Generator in case CPACK_RESOURCE_FILE_LICENSE is in an unsupported format or the .txt -> .rtf conversion does not work as expected.

CPACK_WIX_PRODUCT_ICON
    The Icon shown next to the program name in Add/Remove programs.

    If set, this icon is used in place of the default icon.

CPACK_WIX_UI_REF
    This variable allows you to override the Id of the <UIRef> element in the WiX template.

    The default is WixUI_InstallDir in case no CPack components have been defined and WixUI_FeatureTree otherwise.

CPACK_WIX_UI_BANNER
    The bitmap will appear at the top of all installer pages other than the welcome and completion dialogs.

    If set, this image will replace the default banner image.

    This image must be 493 by 58 pixels.

CPACK_WIX_UI_DIALOG
    Background bitmap used on the welcome and completion dialogs.

    If this variable is set, the installer will replace the default dialog image.

    This image must be 493 by 312 pixels.

CPACK_WIX_PROGRAM_MENU_FOLDER
    Start menu folder name for launcher.

    If this variable is not set, it will be initialized with CPACK_PACKAGE_NAME

    If this variable is set to ., then application shortcuts will be created directly in the start menu and the uninstaller shortcut will be omitted.

CPACK_WIX_CULTURES
    Language(s) of the installer

    Languages are compiled into the WixUI extension library. To use them, simply provide the name of the culture. If you specify more than one culture identifier in a comma or semicolon delimited list, the first one that is found will be used. You can find a list of supported languages at: http://wix.sourceforge.net/manual-wix3/WixUI_localization.htm

CPACK_WIX_TEMPLATE
    Template file for WiX generation

    If this variable is set, the specified template will be used to generate the WiX wxs file. This should be used if further customization of the output is required.

    If this variable is not set, the default MSI template included with CMake will be used.

CPACK_WIX_PATCH_FILE
    Optional list of XML files with fragments to be inserted into generated WiX sources

    This optional variable can be used to specify an XML file that the WIX generator will use to inject fragments into its generated source files.

    Patch files understood by the CPack WIX generator roughly follow this RELAX NG compact schema:

    start = CPackWiXPatch
    CPackWiXPatch = element CPackWiXPatch { CPackWiXFragment* }
    CPackWiXFragment = element CPackWiXFragment
    {
        attribute Id { string },
        fragmentContent*
    }
    fragmentContent = element * - CPackWiXFragment
    {
        (attribute * { text } | text | fragmentContent)*
    }

    Currently fragments can be injected into most Component, File, Directory and Feature elements.

    The following additional special Ids can be used:

•   #PRODUCT for the <Product> element.

•   #PRODUCTFEATURE for the root <Feature> element.

    The following example illustrates how this works.

    Given that the WIX generator creates the following XML element:

    <Component Id="CM_CP_applications.bin.my_libapp.exe" Guid="*"/>

    The following XML patch file may be used to inject an Environment element into it:

    <CPackWiXPatch>
      <CPackWiXFragment Id="CM_CP_applications.bin.my_libapp.exe">
        <Environment Id="MyEnvironment" Action="set"
          Name="MyVariableName" Value="MyVariableValue"/>
      </CPackWiXFragment>
    </CPackWiXPatch>

CPACK_WIX_EXTRA_SOURCES
    Extra WiX source files

    This variable provides an optional list of extra WiX source files (.wxs) that should be compiled and linked. The full path to source files is required.

CPACK_WIX_EXTRA_OBJECTS
    Extra WiX object files or libraries

    This variable provides an optional list of extra WiX object (.wixobj) and/or WiX library (.wixlib) files. The full path to objects and libraries is required.

CPACK_WIX_EXTENSIONS
    This variable provides a list of additional extensions for the WiX tools light and candle.

CPACK_WIX_<TOOL>_EXTENSIONS
    This is the tool specific version of CPACK_WIX_EXTENSIONS. <TOOL> can be either LIGHT or CANDLE.

CPACK_WIX_<TOOL>_EXTRA_FLAGS
    This list variable allows you to pass additional flags to the WiX tool <TOOL>.

    Use it at your own risk. Future versions of CPack may generate flags which may be in conflict with your own flags.

    <TOOL> can be either LIGHT or CANDLE.

CPACK_WIX_CMAKE_PACKAGE_REGISTRY
    If this variable is set the generated installer will create an entry in the windows registry key HKEY_LOCAL_MACHINE\Software\Kitware\CMake\Packages\<PackageName> The value for <PackageName> is provided by this variable.

    Assuming you also install a CMake configuration file this will allow other CMake projects to find your package with the find_package() command.

CPACK_WIX_PROPERTY_<PROPERTY>
    This variable can be used to provide a value for the Windows Installer property <PROPERTY>

    The following list contains some example properties that can be used to customize information under “Programs and Features” (also known as “Add or Remove Programs”)

•   ARPCOMMENTS - Comments

•   ARPHELPLINK - Help and support information URL

•   ARPURLINFOABOUT - General information URL

•   ARPURLUPDATEINFO - Update information URL

•   ARPHELPTELEPHONE - Help and support telephone number

•   ARPSIZE - Size (in kilobytes) of the application

CPACK_WIX_ROOT_FEATURE_TITLE
    Sets the name of the root install feature in the WIX installer. Same as CPACK_COMPONENT_<compName>_DISPLAY_NAME for components.

CPACK_WIX_ROOT_FEATURE_DESCRIPTION
    Sets the description of the root install feature in the WIX installer. Same as CPACK_COMPONENT_<compName>_DESCRIPTION for components.

CPACK_WIX_SKIP_PROGRAM_FOLDER
    If this variable is set to true, the default install location of the generated package will be CPACK_PACKAGE_INSTALL_DIRECTORY directly. The install location will not be located relatively below ProgramFiles or ProgramFiles64.

    NOTE: Installers created with this feature do not take differences between the system on which the installer is created and the system on which the installer might be used into account.

    It is therefore possible that the installer e.g. might try to install onto a drive that is unavailable or unintended or a path that does not follow the localization or convention of the system on which the installation is performed.

CPACK_WIX_ROOT_FOLDER_ID
    This variable allows specification of a custom root folder ID. The generator specific <64> token can be used for folder IDs that come in 32-bit and 64-bit variants. In 32-bit builds the token will expand empty while in 64-bit builds it will expand to 64.

    When unset generated installers will default installing to ProgramFiles<64>Folder.

CPACK_WIX_ROOT
    This variable can optionally be set to the root directory of a custom WiX Toolset installation.

    When unspecified CPack will try to locate a WiX Toolset installation via the WIX environment variable instead.

CPACK_WIX_CUSTOM_XMLNS
    This variable provides a list of custom namespace declarations that are necessary for using WiX extensions. Each declaration should be in the form name=url, where name is the plain namespace without the usual xmlns: prefix and url is an unquoted namespace url. A list of commonly known WiX schemata can be found here: https://wixtoolset.org/documentation/manual/v3/xsd/
