| # - MACRO_OPTIONAL_FIND_PACKAGE() combines FIND_PACKAGE() with an OPTION() |
| # 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() |
