@climbfuji Thanks for updating and modernizing the cmake file.
Have you tested in the UFS?

No, neither this nor the corresponding ccpp-physics PR NCAR/ccpp-physics#1119

I can do the tests this week.

I opened a PR into the SCM with these and the physics changes for testing via CI, NCAR/ccpp-scm#568
