+# CMakeParseArguments
+# -------------------
+#
+# This module once implemented the :command:`cmake_parse_arguments` command
+# that is now implemented natively by CMake.  It is now an empty placeholder
+# for compatibility with projects that include it to get the command from
+# CMake 3.4 and lower.
