Suppress OpenMP messages from FindBLAS, master branch (2021.12.10.)
Silenced the messages from FindOpenMP.cmake while looking for the BLAS library.
CMake's FindBLAS.cmake module looks for OpenMP when looking for a static version of the OpenBLAS library. Even if it doesn't necessarily need OpenMP for that library. This can result in a couple of "package not found" messages, even though BLAS itself is found and is functional.
This is a pretty brute-force method for just silencing any output from FindOpenMP.cmake
while FindBLAS.cmake
is doing its job.
This MR is a replacement for athena!49002 (closed), and a fix for AGENE-2118.
