CPack IFW Generator ------------------- .. versionadded:: 3.1 Configure and run the Qt Installer Framework to generate a Qt installer. .. only:: html .. contents:: Overview ^^^^^^^^ This :manual:`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 :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`_. Variables ^^^^^^^^^ You can use the following variables to change the behavior of the CPack ``IFW`` generator. Debug """"" .. variable:: CPACK_IFW_VERBOSE .. versionadded:: 3.3 Set to ``ON`` to enable addition debug output. By default is ``OFF``. Package """"""" .. variable:: CPACK_IFW_PACKAGE_TITLE Name of the installer as displayed on the title bar. If not specified, it defaults to :variable:`CPACK_PACKAGE_DESCRIPTION_SUMMARY`. .. variable:: CPACK_IFW_PACKAGE_PUBLISHER Publisher of the software (as shown in the Windows Control Panel). If not specified, it defaults to :variable:`CPACK_PACKAGE_VENDOR`. .. variable:: CPACK_IFW_PRODUCT_URL URL to a page that contains product information on your web site. .. variable:: CPACK_IFW_PACKAGE_ICON Filename for a custom installer icon. It must be an absolute path. This should be a ``.icns`` file on macOS and a ``.ico`` file on Windows. It is ignored on other platforms. .. variable:: CPACK_IFW_PACKAGE_WINDOW_ICON Filename for a custom window icon in PNG format for the Installer application. It must be an absolute path. .. variable:: CPACK_IFW_PACKAGE_LOGO Filename for a logo image in PNG format, used as ``QWizard::LogoPixmap``. It must be an absolute path. .. variable:: CPACK_IFW_PACKAGE_WATERMARK .. versionadded:: 3.8 Filename for a watermark image in PNG format, used as ``QWizard::WatermarkPixmap``. It must be an absolute path. .. variable:: CPACK_IFW_PACKAGE_BANNER .. versionadded:: 3.8 Filename for a banner image in PNG format, used as ``QWizard::BannerPixmap``. It must be an absolute path. .. variable:: CPACK_IFW_PACKAGE_BACKGROUND .. versionadded:: 3.8 Filename for a background image in PNG format, used as ``QWizard::BackgroundPixmap`` (only used by ``MacStyle``). It must be an absolute path. .. variable:: CPACK_IFW_PACKAGE_WIZARD_STYLE .. versionadded:: 3.8 Wizard style to be used (``Modern``, ``Mac``, ``Aero`` or ``Classic``). .. variable:: CPACK_IFW_PACKAGE_WIZARD_DEFAULT_WIDTH .. versionadded:: 3.8 Default width of the wizard in pixels. Setting a banner image will override this. .. variable:: CPACK_IFW_PACKAGE_WIZARD_DEFAULT_HEIGHT .. versionadded:: 3.8 Default height of the wizard in pixels. Setting a watermark image will override this. .. variable:: CPACK_IFW_PACKAGE_WIZARD_SHOW_PAGE_LIST .. versionadded:: 3.20 Set to ``OFF`` if the widget listing installer pages on the left side of the wizard should not be shown. It is ``ON`` by default, but will only have an effect if using QtIFW 4.0 or later. .. variable:: CPACK_IFW_PACKAGE_TITLE_COLOR .. versionadded:: 3.8 Color of the titles and subtitles (takes an HTML color code, such as ``#88FF33``). .. variable:: CPACK_IFW_PACKAGE_STYLE_SHEET .. versionadded:: 3.15 Filename for a stylesheet. It must be an absolute path. .. variable:: CPACK_IFW_TARGET_DIRECTORY Default target directory for installation. If :variable:`CPACK_PACKAGE_INSTALL_DIRECTORY` is set, this defaults to ``@ApplicationsDir@/${CPACK_PACKAGE_INSTALL_DIRECTORY}``. If that variable isn't set either, the default used is ``@RootDir@/usr/local``. Predefined variables of the form ``@...@`` are expanded by the `QtIFW scripting engine `_. .. variable:: CPACK_IFW_ADMIN_TARGET_DIRECTORY Default target directory for installation with administrator rights. You can use predefined variables. .. variable:: CPACK_IFW_PACKAGE_REMOVE_TARGET_DIR .. versionadded:: 3.11 Set to ``OFF`` if the target directory should not be deleted when uninstalling. Is ``ON`` by default .. variable:: CPACK_IFW_PACKAGE_GROUP The group, which will be used to configure the root package. .. variable:: CPACK_IFW_PACKAGE_NAME The root package name, which will be used if the configuration group is not specified. .. variable:: CPACK_IFW_PACKAGE_START_MENU_DIRECTORY .. versionadded:: 3.3 Name of the default program group for the product in the Windows Start menu. If not specified, it defaults to :variable:`CPACK_IFW_PACKAGE_NAME`. .. variable:: CPACK_IFW_PACKAGE_MAINTENANCE_TOOL_NAME .. versionadded:: 3.3 Filename of the generated maintenance tool. The platform-specific executable file extension will be appended. If not specified, QtIFW provides a default name (``maintenancetool``). .. variable:: CPACK_IFW_PACKAGE_MAINTENANCE_TOOL_INI_FILE .. versionadded:: 3.3 Filename for the configuration of the generated maintenance tool. If not specified, QtIFW uses a default file name (``maintenancetool.ini``). .. variable:: CPACK_IFW_PACKAGE_ALLOW_NON_ASCII_CHARACTERS .. versionadded:: 3.3 Set to ``ON`` if the installation path can contain non-ASCII characters. Only supported for QtIFW 2.0 and later. Older QtIFW versions will always allow non-ASCII characters. .. variable:: CPACK_IFW_PACKAGE_ALLOW_SPACE_IN_PATH .. versionadded:: 3.3 Set to ``OFF`` if the installation path cannot contain space characters. Is ``ON`` for QtIFW less 2.0 tools. .. variable:: CPACK_IFW_PACKAGE_DISABLE_COMMAND_LINE_INTERFACE .. versionadded:: 3.23 Set to ``ON`` if command line interface features should be disabled. It is ``OFF`` by default and will only have an effect if using QtIFW 4.0 or later. .. variable:: CPACK_IFW_PACKAGE_CONTROL_SCRIPT .. versionadded:: 3.3 Filename for a custom installer control script. .. variable:: CPACK_IFW_PACKAGE_RESOURCES .. versionadded:: 3.7 List of additional resources (``.qrc`` files) to include in the installer binary. They should be specified as absolute paths and no two resource files can have the same file name. You can use the :command:`cpack_ifw_add_package_resources` command to resolve relative paths. .. variable:: CPACK_IFW_PACKAGE_FILE_EXTENSION .. versionadded:: 3.10 The target binary extension. On Linux, the name of the target binary is automatically extended with ``.run``, if you do not specify the extension. On Windows, the target is created as an application with the extension ``.exe``, which is automatically added, if not supplied. On Mac, the target is created as an DMG disk image with the extension ``.dmg``, which is automatically added, if not supplied. .. variable:: CPACK_IFW_REPOSITORIES_ALL The list of remote repositories. The default value of this variable is computed by CPack and contains all repositories added with :command:`cpack_ifw_add_repository` or updated with :command:`cpack_ifw_update_repository`. .. variable:: CPACK_IFW_DOWNLOAD_ALL If this is ``ON``, all components will be downloaded. If not set, the behavior is determined by whether :command:`cpack_configure_downloads` has been called with the ``ALL`` option or not. .. variable:: CPACK_IFW_PACKAGE_PRODUCT_IMAGES .. versionadded:: 3.23 A list of images to be shown on the ``PerformInstallationPage``. These must be absolute paths and the images must be in PNG format. This feature is available for QtIFW 4.0.0 and later. .. variable:: CPACK_IFW_PACKAGE_RUN_PROGRAM .. versionadded:: 3.23 Command executed after the installer is finished, if the user accepts the action. Provide the full path to the application, as found when installed. This typically means the path should begin with the QtIFW predefined variable ``@TargetDir@``. This feature is available for QtIFW 4.0.0 and later. .. variable:: CPACK_IFW_PACKAGE_RUN_PROGRAM_ARGUMENTS .. versionadded:: 3.23 List of arguments passed to the program specified in :variable:`CPACK_IFW_PACKAGE_RUN_PROGRAM`. This feature is available for QtIFW 4.0.0 and later. .. variable:: CPACK_IFW_PACKAGE_RUN_PROGRAM_DESCRIPTION .. versionadded:: 3.23 Text shown next to the check box for running the program after the installation. If :variable:`CPACK_IFW_PACKAGE_RUN_PROGRAM` is set but no description is provided, QtIFW will use a default message like ``Run now``. 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 app bundle. Only available on macOS, ignored on other platforms. .. variable:: CPACK_IFW_ARCHIVE_FORMAT .. versionadded:: 3.23 Set the format used when packaging new component data archives. If you omit this option, the ``7z`` format will be used as a default. Supported formats: * 7z * zip * tar.gz * tar.bz2 * tar.xz .. note:: If the Qt Installer Framework tools were built without libarchive support, only ``7z`` format is supported. This feature is available for QtIFW 4.2.0 and later. .. variable:: CPACK_IFW_ARCHIVE_COMPRESSION .. versionadded:: 3.23 Archive compression level. The allowable values are: * 0 (*No compression*) * 1 (*Fastest compression*) * 3 (*Fast compression*) * 5 (*Normal compression*) * 7 (*Maximum compression*) * 9 (*Ultra compression*) If this variable is not set, QtIFW will use a default compression level, which will typically be 5 (*Normal compression*). .. note:: Some formats do not support all the possible values. For example ``zip`` compression only supports values from 1 to 7. This feature is available for QtIFW 4.2.0 and later. Components """""""""" .. variable:: CPACK_IFW_RESOLVE_DUPLICATE_NAMES Resolve duplicate names when installing components with groups. .. variable:: CPACK_IFW_PACKAGES_DIRECTORIES Additional prepared packages directories that will be used to resolve dependent components. .. variable:: CPACK_IFW_REPOSITORIES_DIRECTORIES .. versionadded:: 3.10 Additional prepared repository directories that will be used to resolve and repack dependent components. This feature is available for QtIFW 3.1 and later. 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 The path to ``archivegen``. .. variable:: CPACK_IFW_BINARYCREATOR_EXECUTABLE The path to ``binarycreator``. .. variable:: CPACK_IFW_REPOGEN_EXECUTABLE 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" ) See Also ^^^^^^^^ Qt Installer Framework Manual: * Index page: https://doc.qt.io/qtinstallerframework/index.html * Component Scripting: https://doc.qt.io/qtinstallerframework/scripting.html * Predefined Variables: https://doc.qt.io/qtinstallerframework/scripting.html#predefined-variables * Promoting Updates: https://doc.qt.io/qtinstallerframework/ifw-updates.html Download Qt Installer Framework for your platform from Qt site: https://download.qt.io/official_releases/qt-installer-framework
