Looks good to me but for some reason, CI tests are failing. I'm looking into that. Also including fesom2.7 into the esm_tests

FESOM is failing to compile in the first test I ran. See /work/ab0246/a270152/testing/comp/fesom/fesom-2.7/comp.out

I thought it was a good idea to turn OMP on by default. Seems thats not the case.

Two solutions:
a) turn omp off in the fesom 2.7 in the comp_command.
b) make a change in the cmakelist.txt in fesom to prevent this error:

if(${ENABLE_OPENMP})
   target_link_libraries(${PROJECT_NAME}.x PRIVATE OpenMP::OpenMP_Fortran)
endif()

I suggest we do both. a) for a quick fix now, b) for 2.7.1.

The errors during compilation still persist after having set -DOPENMP=OFF. See agian /work/ab0246/a270152/testing/comp/fesom/fesom-2.7/comp.out

Sorry for the long wait. Can you do the test again? It seems to have been cleaned up.
