+# MACRO_OPTIONAL_FIND_PACKAGE( <name> [QUIT] )
+# This macro is a combination of OPTION() and FIND_PACKAGE(), it
+# works like FIND_PACKAGE(), but additionally it automatically creates
+# an option name WITH_<name>, which can be disabled via the cmake GUI.
+# or via -DWITH_<name>=OFF
+# The standard <name>_FOUND variables can be used in the same way
+# as when using the normal FIND_PACKAGE()
