This is necessary because custom commands and targets may create custom files whose names are determined by generator expressions. For example, clang should be using $<TARGET_FILE> and $<TARGET_FILE_DIR> instead of reverse engineering the output file name: http://thread.gmane.org/gmane.comp.compilers.clang.scm/80523 However, that can only be done when ADDITIONAL_MAKE_CLEAN_FILES also accepts and evaluates generator expressions. Similarly, KDE uses the LOCATION property where $<TARGET_FILE> would also be better in KDE4_HANDLE_RPATH_FOR_EXECUTABLE but also appends the result to ADDITIONAL_MAKE_CLEAN_FILES. After this patch, both can be ported to generator expressions.
