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.
