# - MACRO_ADD_FILE_DEPENDENCIES(<_file> depend_files...)
# Using the macro MACRO_ADD_FILE_DEPENDENCIES() is discouraged. There are usually
# better ways to specify the correct dependencies.
#
# MACRO_ADD_FILE_DEPENDENCIES(<_file> depend_files...) is just a convenience
# wrapper around the OBJECT_DEPENDS source file property. You can just
# use set_property(SOURCE <file> APPEND PROPERTY OBJECT_DEPENDS depend_files) instead.
