CPack IFW Generator

New in version 3.1.

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

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.

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

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"
  )
