# CPack IFW Generator

See `CPackIFW` for details on the CPackIFW module.

## Overview

CPack `IFW` generator helps you to create online and offline binary cross-platform installers with a graphical user interface.

CPack IFW generator prepares project installation and generates configuration and meta information for QtIFW tools.

The QtIFW provides a set of tools and utilities to create installers for the supported desktop Qt platforms: Linux, Microsoft Windows, and macOS.

You should also install QtIFW to use CPack `IFW` generator.

## Hints

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.

## 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_IFW_PACKAGE_FILE_EXTENSION`

## Online installer

By default CPack IFW generator makes offline installer. This means that all components will be packaged into a binary file.

To make a component downloaded, you must set the `DOWNLOADED` option in `cpack_add_component()`.

Then you would use the command `cpack_configure_downloads()`. If you set `ALL` option all components will be downloaded.

You also can use command `cpack_ifw_add_repository()` and variable `CPACK_IFW_DOWNLOAD_ALL` for more specific configuration.

CPack IFW generator creates “repository” dir in current binary dir. You would copy content of this dir to specified `site` (`url`).
