# 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. If you don’t use a default path for the installation, please set the used path in the variable `QTIFWDIR`.

## Variables

You can use the following variables to change behavior of CPack `IFW` generator.

## Commands

The module defines the following commands:

`cpack_ifw_configure_component`

Sets the arguments specific to the CPack IFW generator.

    cpack_ifw_configure_component(<compname> [COMMON]
                        [NAME <name>]
                        [VERSION <version>]
                        [SCRIPT <script>]
                        [PRIORITY <priority>]
                        [DEPENDS <com_id> ...]
                        [LICENSES <display_name> <file_path> ...])

This command should be called after cpack_add_component command.

`COMMON` if set, then the component will be packaged and installed as part of a group to which it belongs.

`VERSION` is version of component. By default used `CPACK_PACKAGE_VERSION`.

`SCRIPT` is a relative or absolute path to operations script for this component.

`NAME` is used to create domain-like identification for this component. By default used origin component name.

`PRIORITY` is priority of the component in the tree.

`DEPENDS` list of dependency component identifiers in QtIFW style.

`LICENSES` pair of <display_name> and <file_path> of license text for this component. You can specify more then one license.

`cpack_ifw_configure_component_group`

Sets the arguments specific to the CPack IFW generator.

    cpack_ifw_configure_component_group(<grpname>
                        [VERSION <version>]
                        [NAME <name>]
                        [SCRIPT <script>]
                        [PRIORITY <priority>]
                        [LICENSES <display_name> <file_path> ...])

This command should be called after cpack_add_component_group command.

`VERSION` is version of component group. By default used `CPACK_PACKAGE_VERSION`.

`NAME` is used to create domain-like identification for this component group. By default used origin component group name.

`SCRIPT` is a relative or absolute path to operations script for this component group.

`PRIORITY` is priority of the component group in the tree.

`LICENSES` pair of <display_name> and <file_path> of license text for this component group. You can specify more then one license.

`cpack_ifw_add_repository`

Add QtIFW specific remote repository.

    cpack_ifw_add_repository(<reponame> [DISABLED]
                        URL <url>
                        [USERNAME <username>]
                        [PASSWORD <password>]
                        [DISPLAY_NAME <display_name>])

This macro 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.

## 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")
    cpack_ifw_configure_component(myapp
        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`).
