No functional change, this adds LIB definition and args to cmake files. Without this it's difficult to migrate away from 'BLENDER_SORTED_LIBS' since there are many platforms/configurations that could break when changing linking order. Manually add and enable WITHOUT_SORTED_LIBS to try building without sorted libs (currently fails since all variables are empty). This check will eventually be removed. See T46725.
