Name clash with g2/v3.4.9 and w3emc/v2.10.0

[DavidHuber-NOAA]

What is wrong?

The vint executable reports a duplicate module name when building with g2/v3.4.9 and w3emc/v2.10.0:

What should have happened?

The vint linker should pull the skgb module from either g2 or w3emc.

What machines are impacted?

All or N/A

Steps to reproduce

On Hera:

git clone [email protected]:DavidHuber-NOAA/gfs-utils -b feature/ss_1.8.0
cd gfs-utils/ush
./build.sh

Additional information

Found while testing a version bump for spack-stack release 1.8.0.

Do you have a proposed solution?

Perhaps update the CMakeLists.txt file for vint.

[DavidHuber-NOAA]

The fix will be to remove w3emc from the CMakeLists.txt file for vint and tave as the skgb module has been added to g2.

[mark-a-potts]

I have a patch that I can add to the global-workflow repo and will get applied by build_gfs_utils.sh if spack_stack_ver = 1.8.0.
