CMake Error at buildlib/RDMA_EnableCStd.cmake:63 (CHECK_C_SOURCE_COMPILES):
Unknown CMake command "CHECK_C_SOURCE_COMPILES".

A difference between passing and failing build root is at <https://koschei.fedoraproject.org/build/15603625>. An upgrade of cmake from 3.26.4-4.fc39 to 3.27.0~rc1-1.fc39 looks suspicious.
Reproducible: Always
