Hi,


We are porting MariaDB (10.3.7 now) on AIX.


On some machines we have the following error message when running:

In file:  mariadb-10.3.7/64bit/CMakeFiles/CMakeTmp/CMakeLists.txt   , there is:

Talking with CMake guys, they said:

> That's broken here:
https://github.com/MariaDB/server/blob/ed0b84a0270bd99b001dd00654875d26e29b9432/plugin/auth_gssapi/cmake/FindGSSAPI.cmake#L56

Do you have an idea about what is broken and what should be changed? either on AIX or for all target?


Thanks/Regards,


Cordialement,
