# - Functions to help assemble a standalone Qt4 executable.
# A collection of CMake utility functions useful for deploying
# Qt4 executables.
#
# The following functions are provided by this module:
# write_qt4_conf
# resolve_qt4_paths
# fixup_qt4_executable
# install_qt4_plugin_path
# install_qt4_plugin
# install_qt4_executable
# Requires CMake 2.6 or greater because it uses function and
# PARENT_SCOPE. Also depends on BundleUtilities.cmake.
#
# WRITE_QT4_CONF(<qt_conf_dir> <qt_conf_contents>)
# Writes a qt.conf file with the <qt_conf_contents> into <qt_conf_dir>.
#
# RESOLVE_QT4_PATHS(<paths_var> [<executable_path>])
# Loop through <paths_var> list and if any don't exist resolve them
# relative to the <executable_path> (if supplied) or the CMAKE_INSTALL_PREFIX.
#
# FIXUP_QT4_EXECUTABLE(<executable> [<qtplugins> <libs> <dirs> <plugins_dir> <request_qt_conf>])
# Copies Qt plugins, writes a Qt configuration file (if needed) and fixes up a
# Qt4 executable using BundleUtilities so it is standalone and can be
# drag-and-drop copied to another machine as long as all of the system
# libraries are compatible.
#
# <executable> should point to the executable to be fixed-up.
#
# <qtplugins> should contain a list of the names or paths of any Qt plugins
# to be installed.
#
# <libs> will be passed to BundleUtilities and should be a list of any already
# installed plugins, libraries or executables to also be fixed-up.
#
# <dirs> will be passed to BundleUtilities and should contain and directories
# to be searched to find library dependencies.
#
# <plugins_dir> allows an custom plugins directory to be used.
#
# <request_qt_conf> will force a qt.conf file to be written even if not needed.
#
# INSTALL_QT4_PLUGIN_PATH(plugin executable copy installed_plugin_path_var <plugins_dir> <component> <configurations>)
# Install (or copy) a resolved <plugin> to the default plugins directory
# (or <plugins_dir>) relative to <executable> and store the result in
# <installed_plugin_path_var>.
#
# If <copy> is set to TRUE then the plugins will be copied rather than
# installed. This is to allow this module to be used at CMake time rather than
# install time.
#
# If <component> is set then anything installed will use this COMPONENT.
#
# INSTALL_QT4_PLUGIN(plugin executable copy installed_plugin_path_var <plugins_dir> <component>)
# Install (or copy) an unresolved <plugin> to the default plugins directory
# (or <plugins_dir>) relative to <executable> and store the result in
# <installed_plugin_path_var>. See documentation of INSTALL_QT4_PLUGIN_PATH.
#
# INSTALL_QT4_EXECUTABLE(<executable> [<qtplugins> <libs> <dirs> <plugins_dir> <request_qt_conf>])
# Installs Qt plugins, writes a Qt configuration file (if needed) and fixes up
# a Qt4 executable using BundleUtilities so it is standalone and can be
# drag-and-drop copied to another machine as long as all of the system
# libraries are compatible. The executable will be fixed-up at install time.
# See documentation of FIXUP_QT4_BUNDLE.
