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.

  else ()
    set(_deps ${ARGN})

  set_source_files_properties(${_file} PROPERTIES OBJECT_DEPENDS "${_deps}")
