[Ncep.list.fv3-announce] Using FMS as a library in UFS

[Jun Wang - NOAA Federal]

Fanglin,

You don't need to build the hpc-stack when debugging FMS. You can build an
FMS library following the instructions on the GFDL FMS website on how to
build FMS library, then add the FMS_ROOT at the compile line: cmake
-DFMS_ROOT=/path/to/my/fms/install .... Sorry for the confusion.
