# --------
#
# .. _QtIFW: http://qt-project.org/doc/qtinstallerframework/index.html
#
# 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 create online and offline
# binary cross-platform installers with a graphical user interface.
#
# CPack IFW generator prepare project installation and generate 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.
#
# To use CPack ``IFW`` generator you must also install QtIFW_.
# If you are not using the default path for the installation, please set
# the path to the variable ``QTIFWDIR``.
#
# Variables
# ^^^^^^^^^

# --------------------------------------------------------------------------
#
# .. command:: cpack_ifw_configure_component
#
# Sets the arguments specific to the CPack IFW generator.
#
# ::
#
#   cpack_ifw_configure_component(<compname> [COMMON]
#                       [NAME <name>]
#                       [VERSION <version>]

#                       [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 he belongs.
#
# ``VERSION`` is version of component.
# By default used :variable:`CPACK_PACKAGE_VERSION`.
#
# ``SCRIPT`` is 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.
#
# --------------------------------------------------------------------------
#
# .. command:: 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 :variable:`CPACK_PACKAGE_VERSION`.
#
# ``NAME`` is used to create domain-like identification for this component group.
# By default used origin component group name.
#
# ``SCRIPT`` is 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.
#
# --------------------------------------------------------------------------
#
# .. command:: cpack_ifw_add_repository
#
# Add QtIFW_ specific remote repository.
#
# ::
#
#   cpack_ifw_add_repository(<reponame> [DISABLED]
#                       URL <url>
#                       [USERNAME <username>]

#
# This macro will also add the <reponame> repository
# to a variable :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
# ^^^^^^^^^^^^^
#
# .. code-block:: cmake
#
#    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 defaul CPack IFW generator make 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
# :command:`cpack_add_component`.
#
# Then you would use the command :command:`cpack_configure_downloads`.
# If you set ``ALL`` option all components will be downloaded.
#
# You also can use command :command:`cpack_ifw_add_repository` and
# variable :variable:`CPACK_IFW_DOWNLOAD_ALL` for more specific configuration.
#
# CPack IFW generator create "repository" dir in current binary dir. You
# would copy content of this dir to specified ``site`` (``url``).
