Split C/Fortran netCDF installations fails with multiple library directories in CMake

[scrasmussen]

Expected Behavior

CMake build finds the Fortran NetCDF library when the NetCDF C and Fortran installation are in different directories.

Current Behavior

The line

    find_library (NETCDF_LIBRARIES_${lang} NAMES ${libs}  HINTS "${NetCDF_lib_dirs}" NO_DEFAULT_PATH)

is only searching the path where the C library is installed, but the Fortran NetCDF library is installed is a separate directory.

Possible Solution

Choose one of the following or maybe something else

• Edit this line in FindNetCDF.cmake so it can find the Fortran NetCDF installation.
  • Add another HINT variable that would point to the Fortran Path
  • Removing NO_DEFAULT_PATH worked
• Have a CMakeLists.txt or the FindNetCDF.cmake file extract and use the path from nf-config --flibs, it will have the Fortran installation.

Steps to Reproduce (for bugs)

1. On Cheyenne load the JEDI Spack modules

   
   module purge
   export LMOD_TMOD_FIND_FIRST=yes

module use /glade/work/jedipara/cheyenne/spack-stack/modulefiles/misc module load miniconda/3.9.12 module load ecflow/5.8.4 module load mysql/8.0.31

module use /glade/work/epicufsrt/contrib/spack-stack/spack-stack-1.4.0/envs/unified-env-v2/install/modulefiles/Core module load stack-gcc/10.1.0 module load stack-openmpi/4.1.1 module load stack-python/3.9.12 module load jedi-base-env

2. Try and build WRF-Hydro with basic CMake commands: `mkdir build; cd build; cmake ..`

## Your Environment
* Version of the code used: `main` branch
* Operating System and version: Cheyenne
* Compiler and version: GNU 10.1.0
* Other relevant information: Using Spack Modules so NetCDF C and Fortran installations are in different directories
