| 2 | # MACRO_OPTIONAL_FIND_PACKAGE( <name> [QUIT] ) |
| 3 | # This macro is a combination of OPTION() and FIND_PACKAGE(), it |
| 4 | # works like FIND_PACKAGE(), but additionally it automatically creates |
| 5 | # an option name WITH_<name>, which can be disabled via the cmake GUI. |
| 6 | # or via -DWITH_<name>=OFF |
| 7 | # The standard <name>_FOUND variables can be used in the same way |
| 8 | # as when using the normal FIND_PACKAGE() |
