[netCDF #UWC-650183]: netCDF-Fortran 4.5.2

Hello,

LIBS is a valid environmental variable used by the linker; this environmental 
variable is telling the linker to attempt to link against these libraries.  
From what you provided, it appears that the issue is the compiler and linker 
are not finding libnetcdf when it attempts to link.  This can be controlled by 
setting the environment variable LDFLAGS="path to directory containing 
libnetcdf".  

It looks like you're working with WRF; I'm afraid I don't have any experience 
with WRF specifically, you might also reach out to the WRF maintainers to see 
if they can provide additional information.

Have a great day,

-Ward
