 CPack IFW Generator
 -------------------

 .. versionadded:: 3.1

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

 Overview
 ^^^^^^^^

 This :manual:`cpack generator <cpack-generators(7)>` generates
 configuration and meta information for the `Qt Installer Framework
 <http://doc.qt.io/qtinstallerframework/index.html>`_ (QtIFW),
 and runs QtIFW tools to generate a Qt installer.

 QtIFW provides tools and utilities to create installers for
 the platforms supported by `Qt <https://www.qt.io>`_: Linux,
 Microsoft Windows, and macOS.

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

  This feature is available for QtIFW 4.0.0 and later.

 .. variable:: CPACK_IFW_PACKAGE_SIGNING_IDENTITY

  .. versionadded:: 3.23

  Allows specifying a code signing identity to be used for signing the generated

 .. variable:: CPACK_IFW_ARCHIVE_COMPRESSION

  .. versionadded:: 3.23

  Archive compression level. The allowable values are:

 QtIFW Tools
 """""""""""

 .. variable:: CPACK_IFW_FRAMEWORK_VERSION

  .. versionadded:: 3.3

  The version of the QtIFW tools that will be used. This variable is set
  by the :module:`CPackIFW` module.

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

 .. variable:: CPACK_IFW_ARCHIVEGEN_EXECUTABLE

  .. versionadded:: 3.19

 .. variable:: CPACK_IFW_INSTALLERBASE_EXECUTABLE

  The path to ``installerbase``.

 .. variable:: CPACK_IFW_DEVTOOL_EXECUTABLE

  The path to ``devtool``.

 Hints for Finding QtIFW
 """""""""""""""""""""""

 Generally, the CPack ``IFW`` generator automatically finds QtIFW tools.
 The following (in order of precedence) can also be set to augment the
 locations normally searched by :command:`find_program`:

 .. variable:: CPACK_IFW_ROOT

   .. versionadded:: 3.9

   CMake variable

 .. envvar:: CPACK_IFW_ROOT

   .. versionadded:: 3.9

   Environment variable

 .. variable:: QTIFWDIR

   CMake variable

 .. envvar:: QTIFWDIR

   Environment variable

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

 Other Settings
 ^^^^^^^^^^^^^^

 Online installer
 """"""""""""""""

 By default, this generator generates an *offline installer*. This means
 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 :command:`cpack_add_component` command
 specifies that a component is to be downloaded. Alternatively, the ``ALL``
 option in the :command:`cpack_configure_downloads` command specifies that
 `all` components are to be be downloaded.

 The :command:`cpack_ifw_add_repository` command and the
 :variable:`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 :module:`CPackComponent` module, especially the section
 on the :command:`cpack_configure_downloads` function, explains how to make
 these files accessible from a download URL.

 Internationalization
 """"""""""""""""""""

 .. versionadded:: 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 your components and groups.

 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
 after that a set of pairs with the name of the locale and the localized value.

 For example:

 .. code-block:: cmake

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

	The path to ``repogen``.

	.. variable:: CPACK_IFW_INSTALLERBASE_EXECUTABLE

	The path to ``installerbase``.

	.. variable:: CPACK_IFW_DEVTOOL_EXECUTABLE

	The path to ``devtool``.

	Hints for Finding QtIFW
	"""""""""""""""""""""""

	Generally, the CPack ``IFW`` generator automatically finds QtIFW tools.
	The following (in order of precedence) can also be set to augment the
	locations normally searched by :command:`find_program`:

	.. variable:: CPACK_IFW_ROOT

	.. versionadded:: 3.9

	CMake variable

	.. envvar:: CPACK_IFW_ROOT

	.. versionadded:: 3.9

	Environment variable

	.. variable:: QTIFWDIR

	CMake variable

	.. envvar:: QTIFWDIR

	Environment variable

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

	Other Settings
	^^^^^^^^^^^^^^

	Online installer
	""""""""""""""""

	By default, this generator generates an offline installer. This means
	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 :command:`cpack_add_component` command
	specifies that a component is to be downloaded. Alternatively, the ``ALL``
	option in the :command:`cpack_configure_downloads` command specifies that
	`all` components are to be be downloaded.

	The :command:`cpack_ifw_add_repository` command and the
	:variable:`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 :module:`CPackComponent` module, especially the section
	on the :command:`cpack_configure_downloads` function, explains how to make
	these files accessible from a download URL.

	Internationalization
	""""""""""""""""""""

	.. versionadded:: 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 your components and groups.

	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
	after that a set of pairs with the name of the locale and the localized value.

	For example:

	.. code-block:: cmake

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