+# - 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.
