Somehow the CMakeLists.txt doesn't find OpenMP.

From what I see in the error log, it cannot find omp.h file because it doesn't include the /opt/rocm folders.

I have the latest rocm-5.7.1 and I see there the omp.h header.

Any idea what I am missing?

Nevermind. I was missing the libomp-dev package.
