### Finding and including esmf.mk                                         ######
### NOTE: On Yellowstone, ESMF is only available with the intel compilers ######
###       And require running the following:                              ######
###           $ module load esmf                                          ######
###           $ module load esmf-6.1.1-ncdfio-uni-O                       ######
###       The executable should run on the yellowstone login node         ######
