Hello,
This might be a basic issue but cmake is not able to find BLAS for some reason. The system is running CentOS8 and spitting out the error:
…

I have tried installing BLAS with yum and from source but it’s the same problem. Is it necessary some extra flag like -DCBLAS_LIBRARIES=/root/lapack/LIB
or similar? Thanks.
The error file reads:
