CPackIFW — CMake 3.10.2 Documentation

# CPackIFW

This module looks for the location of the command line utilities supplied with the Qt Installer Framework (QtIFW).

The module also defines several commands to control the behavior of the CPack `IFW` generator.

## 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 Mac OS X.

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"
      )

## Variables

  `ESSENTIAL`
    if set, then the package manager stays disabled until that component is updated.
  `VIRTUAL`
    if set, then the component will be hidden from the installer. It is a equivalent of the `HIDDEN` option from the `cpack_add_component()` command.

  `REQUIRES_ADMIN_RIGHTS`
    set it if the component needs to be installed with elevated permissions.
  `NAME`
    is used to create domain-like identification for this component. By default used origin component name.

    keep empty to auto generate.
  `SCRIPT`
    is a relative or absolute path to operations script for this component.
  `PRIORITY` | `SORTING_PRIORITY`

  `AUTO_DEPEND_ON`
    list of identifiers of component or component group in QtIFW style that this component has an automatic dependency on.

`cpack_ifw_add_repository`

  Add QtIFW specific remote repository to binary installer.

      cpack_ifw_add_repository(<reponame> [DISABLED]

                          [DISPLAY_NAME <display_name>])

  This command will also add the <reponame> repository to a variable `CPACK_IFW_REPOSITORIES_ALL`.

  `DISABLED`
    if set, then the repository will be disabled by default.
  `URL`
    is points to a list of available components.
  `USERNAME`
    is used as user on a protected repository.
  `PASSWORD`
    is password to use on a protected repository.
  `DISPLAY_NAME`
    is string to display instead of the URL.

`cpack_ifw_update_repository`

  Update QtIFW specific repository from remote repository.

      cpack_ifw_update_repository(<reponame>
                          [[ADD|REMOVE] URL <url>]|
                           [REPLACE OLD_URL <old_url> NEW_URL <new_url>]]
                          [USERNAME <username>]

                          [DISPLAY_NAME <display_name>])

  This command will also add the <reponame> repository to a variable `CPACK_IFW_REPOSITORIES_ALL`.

  `URL`
    is points to a list of available components.
  `OLD_URL`
    is points to a list that will replaced.
  `NEW_URL`
    is points to a list that will replace to.
  `USERNAME`
    is used as user on a protected repository.
  `PASSWORD`
    is password to use on a protected repository.
  `DISPLAY_NAME`
    is string to display instead of the URL.

`cpack_ifw_add_package_resources`

  Add additional resources in the installer binary.

      cpack_ifw_add_package_resources(<file_path> <file_path> ...)

  This command will also add the specified files to a variable `CPACK_IFW_PACKAGE_RESOURCES`.

## Example usage

    set(CPACK_PACKAGE_NAME "MyPackage")
    set(CPACK_PACKAGE_DESCRIPTION_SUMMARY "MyPackage Installation Example")
    set(CPACK_PACKAGE_VERSION "1.0.0") # Version of installer

    include(CPack)
    include(CPackIFW)

    cpack_add_component(myapp
        DISPLAY_NAME "MyApp"
        DESCRIPTION "My Application") # Default description
    cpack_ifw_configure_component(myapp
        DESCRIPTION ru_RU "Мое Приложение" # Localized description
        VERSION "1.2.3" # Version of component
        SCRIPT "operations.qs")
    cpack_add_component(mybigplugin
        DISPLAY_NAME "MyBigPlugin"
        DESCRIPTION "My Big Downloadable Plugin"
        DOWNLOADED)
    cpack_ifw_add_repository(myrepo
        URL "http://example.com/ifw/repo/myapp"
        DISPLAY_NAME "My Application Repository")

## 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`).
