| +# 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() |
