Cmake run_test and debug fixes

[JessicaMeixner-NOAA]

Pull Request Summary

This provides a bug fix for CMAKE debug option when running with ufs-weather-model and makes sure when you are running with the -S option that run_cmake_test exists before building the code.

Description

Updates for cmake:

• Fix from @kgerheiser for making sure CMAKE debug flags are cleared when WW3 is built from a parent repo, such as the ufs-weather-model
• bug fix for run_cmake_test so that you will exit out before building the model if the -S option is used and the test has already been completed. This will make any resubmission of matrix regression tests significantly faster and was an oversight in the creation of run_cmake_test

Issue(s) addressed

-fixes #646

Commit Message

Update run_cmake test to exit if test is completed before building and clear debug flags in cmake if built from a parent repo.

co-author: @kgerheiser

Check list

• Branch is up to date with the authoritative repository (NOAA-EMC) develop branch.
• Checked the checklist for a developer submitting to develop.
• If a version number update is required, checked the updating version number checklist.
• If a new feature was added, a regression test for testing the new feature is added.

Testing

• How were these changes tested? The ufs-weather-model was run for the debug fix and then I ran the matrix, stopped after a test had completed, and then re-submitted the matrix to ensure that the test was then in fact skipped (before building) as expected.
• Are the changes covered by regression tests? In the ufs-weather-model
• Have the matrix regression tests been run (if yes, please note HPC and compiler)? no

@aliabdolali please let me know if you think the full matrix of regression tests are required for this PR so I can start those tests asap. In addition I'm happy to point you to testing I did with the cmake debug fix for ufs-waether-model that I did yesterday if that would be helpful for your review of this PR.

@jessica, the regtests are submitted this morning, please give me the path to the ufs tests. Also, I am happy with the changes, but let's wait for the tests.
