 # KDevelop Platform Macros
 #
 # The following macros are defined here:
 #
 #  KDEVPLATFORM_ADD_APP_TEMPLATES( template1 ... templateN )
 #    Use this to get packaged template archives for the given app templates.
 #    Parameters should be the directories containing the templates.
 #
 #  KDEVPLATFORM_ADD_FILE_TEMPLATES( template1 ... templateN )
 #    Use this to get packaged template archives for the given file templates.
 #    Parameters should be the directories containing the templates.
 #
 #  KDEVPLATFORM_ADD_PLUGIN( <plugin> JSON <jsonfile> SOURCES <src1> [<src2> [...]] [SKIP_INSTALL] )
 #    Use this to get create plugins for the KDevPlatform.
 #    Parameters should be the json file with plugin metadata and the sources of the plugin.
 #    In case the plugin should not be installed, pass SKIP_INSTALL.
