## 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.

### Debug

### QtIFW Tools

CPACK_IFW_FRAMEWORK_VERSION

  New in version 3.3.

  The version of used QtIFW tools.

The following variables provide the locations of the QtIFW command-line tools as discovered by the module `CPackIFW`. These variables are cached, and may be configured if needed.

CPACK_IFW_ARCHIVEGEN_EXECUTABLE

  New in version 3.19.

  The path to `archivegen`.

CPACK_IFW_BINARYCREATOR_EXECUTABLE

CPACK_IFW_INSTALLERBASE_EXECUTABLE

  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

  New in version 3.9.

  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

New in version 3.9.

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"
      )
