CPack IFW Generator

Overview

This cpack generator generates configuration and meta information for the Qt Installer Framework (QtIFW).

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 should also be installed. The module CPackIFW looks for the location of the QtIFW command-line utilities.

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_START_MENU_DIRECTORY

Name of the default program group for the product in the Windows Start menu.

By default used CPACK_IFW_PACKAGE_NAME.

CPACK_IFW_TARGET_DIRECTORY

Default target directory for installation. By default used “@ApplicationsDir@/CPACK_PACKAGE_INSTALL_DIRECTORY”

You can use predefined variables.

CPACK_IFW_ADMIN_TARGET_DIRECTORY

Default target directory for installation with administrator rights.

You can use predefined variables.

CPACK_IFW_PACKAGE_GROUP

The group, which will be used to configure the root package

CPACK_IFW_PACKAGE_NAME

The root package name, which will be used if configuration group is not specified

CPACK_IFW_PACKAGE_MAINTENANCE_TOOL_NAME

Filename of the generated maintenance tool. The platform-specific executable file extension is appended.

By default used QtIFW defaults (maintenancetool).

CPACK_IFW_PACKAGE_REMOVE_TARGET_DIR

Set to OFF if the target directory should not be deleted when uninstalling.

Is ON by default

CPACK_IFW_PACKAGE_MAINTENANCE_TOOL_INI_FILE

Filename for the configuration of the generated maintenance tool.

By default used QtIFW defaults (maintenancetool.ini).

CPACK_IFW_PACKAGE_ALLOW_NON_ASCII_CHARACTERS

Set to ON if the installation path can contain non-ASCII characters.

Is ON for QtIFW less 2.0 tools.

CPACK_IFW_PACKAGE_ALLOW_SPACE_IN_PATH

Set to OFF if the installation path cannot contain space characters.

Is ON for QtIFW less 2.0 tools.

CPACK_IFW_PACKAGE_CONTROL_SCRIPT

Filename for a custom installer control script.

CPACK_IFW_PACKAGE_RESOURCES

List of additional resources (‘.qrc’ files) to include in the installer binary.

You can use cpack_ifw_add_package_resources() command to resolve relative paths.

CPACK_IFW_PACKAGE_FILE_EXTENSION

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.

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().

CPACK_IFW_DOWNLOAD_ALL

If this is ON all components will be downloaded. By default is OFF or used value from CPACK_DOWNLOAD_ALL if set

Components

CPACK_IFW_RESOLVE_DUPLICATE_NAMES

Resolve duplicate names when installing components with groups.

CPACK_IFW_PACKAGES_DIRECTORIES

Additional prepared packages dirs that will be used to resolve dependent components.

CPACK_IFW_REPOSITORIES_DIRECTORIES

Additional prepared repository dirs that will be used to resolve and repack dependent components. This feature available only since QtIFW 3.1.

Tools

CPACK_IFW_FRAMEWORK_VERSION

The version of used QtIFW tools.

CPACK_IFW_BINARYCREATOR_EXECUTABLE

The path to “binarycreator” command line client.

This variable is cached and may be configured if needed.

CPACK_IFW_REPOGEN_EXECUTABLE

The path to “repogen” command line client.

This variable is cached and may be configured if needed.

CPACK_IFW_INSTALLERBASE_EXECUTABLE

The path to “installerbase” installer executable base.

This variable is cached and may be configured if needed.

CPACK_IFW_DEVTOOL_EXECUTABLE

The path to “devtool” command line client.

This variable is cached and may be configured if needed.

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).
