Comment (by platipodium):

 Thanks for the updated to ESMF 7.1.0r that was long-awaited (upstream).

 Indeed, with `variant  gfortran`, the cxx compiler used with `openmpi` is
 now used by ESMF despite wrong naming of ESMF_COMPILER variable

 {{{
 ESMF_CXXCOMPILER=/opt/local/bin/mpicxx-openmpi-mp
 ESMF_COMPILER: gfortran
 /opt/local/bin/mpicxx-openmpi-mp --version
 }}}

 So while this de facto address my request, it is still very confusing for
 the user (seeing ESMF_COMPILER=gfortran when she expects
 ESMF_COMPILER=gfortranclang).  I don't know of adverse effects upstream,
 but there might be some ...

 I would like to see a changed variant nomenclature (separately choosing
 one of gcc/clang as c compiler and one of gfortran/g95 as f compiler) and
 a correct representation in the upstream variable ESMF_COMPILER
