ADDITIONAL_CLEAN_FILES ---------------------- Additional files to remove during the clean stage. A :ref:`;-list ` of files that will be removed as a part of the ``clean`` target. Relative paths are allowed and are interpreted relative to the current binary directory. Arguments to :prop_dir:`ADDITIONAL_CLEAN_FILES` may use :manual:`generator expressions `. This property only works for the :generator:`Ninja` and the Makefile generators. It is ignored on other generators.
