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

[Jun Wang - NOAA Federal]

A correction: Developers using other platforms will need to build the FMS
library before building the model executable. It is not required to build
the FMS library under hpc-stack, users just need to specify the FMS_ROOT at
compile time.
