# Set up the embedded resources.
setup_fgfs_embedded_resources()
Integrate the EmbeddedResourceManager into FlightGear ${CMAKE_SOURCE_DIR}/src/EmbeddedResources/FlightGear-resources.xml (currently empty) is automatically "compiled" into ${CMAKE_BINARY_DIR}/src/EmbeddedResources/FlightGear-resources.[ch]xx by fgrcc inside the build directory. These files are incorporated into the FlightGear build (FlightGear-resources.cxx is linked into FlightGear). When the XML embedded resource declaration file added here, FlightGear-resources.xml, is compiled, fgrcc is passed the --root=${CMAKE_SOURCE_DIR} option, so that files referred to in FlightGear-resources.xml are looked up relatively to the root directory of the FlightGear repository. One could use a second XML embedded resource declaration file compiled with a different --root option to grab files from FGData, for instance. I would name such a file FGData-resources.xml to be consistent with the current naming scheme. Note: this --root option applies to the paths of real files. Don't confuse it with the 'prefix' attribute of <qresource> elements inside XML resource declaration files (such as FlightGear-resources.xml), which applies to the virtual path of each resource defined beneath. The commands in src/Main/CMakeLists.txt ensure that FlightGear-resources.xml is recompiled with fgrcc whenever it is changed, and obviously also when FlightGear-resources.cxx or FlightGear-resources.hxx is missing. However, CMake doesn't know how to parse fgrcc XML resource declaration files, therefore when a resource is modified but the XML file it is declared in is not (here, FlightGear-resources.xml), you have to trigger yourself a recompilation of the XML resource declaration file to see the new resource contents inside FlightGear. The easiest ways to do so are: - either update the timestamp of the XML resource declaration file; - or remove one or both of the generated files (FlightGear-resources.cxx and FlightGear-resources.hxx here). The EmbeddedResourceManager is created in fgMainInit() just after Options::processOptions() set the language that was either requested by the user or obtained from the system (locales). Resources from FlightGear-resources.cxx are added to it, after which EmbeddedResourceManager::selectLocale() is called with the user's preferred locale (obtained with FGLocale::getPreferredLanguage()). Upon reset (fgStartNewReset()), EmbeddedResourceManager::selectLocale() is called in a similar way after Options::processOptions(), however in this case the EmbeddedResourceManager instance doesn't have to be recreated.
