Well it tries the following compiler options for openmp.

    oflags = ["-fopenmp", # Gnu
              "-qsmp=omp",# IBM XL C/C++
              "-h omp",   # Cray. Must come after XL because XL interprets this option as meaning "-soname omp"
              "-mp",      # Portland Group
              "-Qopenmp", # Intel windows
              "-openmp",  # Intel
              "-xopenmp", # Sun
              "+Oopenmp", # HP
              "/openmp"   # Microsoft Visual Studio
              ]

I don't know what the flag for fugaku compiler is.
