# KCONFIG_ADD_KCFG_FILES (SRCS_VAR [GENERATE_MOC] [USE_RELATIVE_PATH] file1.kcfgc ... fileN.kcfgc)
# Use this to add KDE config compiler files to your application/library.
# Use optional GENERATE_MOC to generate moc if you use signals in your kcfg files.
# Use optional USE_RELATIVE_PATH to generate the classes in the build following the given
# relative path to the file.
