DeployQt4

DeployQt4

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> <component>])

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. <component> is the COMPONENT used for bundle fixup and plugin installation. See documentation of FIXUP_QT4_BUNDLE.
