See the Testing/* directory.  When not running in dashboard
client mode there isn't much logged though.

I suspect mariadb's source is setting CMAKE_REQUIRED_LIBRARIES
to a space-separated value instead of a ;-separated value.

See the code here:

  https://github.com/MariaDB/server/blob/ed0b84a027/plugin/auth_gssapi/CMakeLists.txt#L22-L24

It assumes GSSAPI_LIBS is ;-separated, but the cache entry you
quoted is a command-lien string with spaces.
