A use of GCHP, @TianYangMY, encountered a CMake failure using Intel Fortran, see https://github.com/geoschem/GCHP/issues/370.
Eventually, it was determined they were using an Hygon processor. The user provided cpuinfo output which lists it as avx2 compatible:

Because of this, -march=core-avx2 should work for Hygon.
