Update model level build system to work with UFS Coastal

[uturuncoglu]

@platipodium @josephzhang8 This PR aims to bring build level updates used under UFS coastal to upstream. I created this since coupling level changes are already merged with the upstream. Please let me know what you think about these changes.

@uturuncoglu

My test cmake threw a lot of errors related to netcdf and util scripts. Also, did you remove the target 'pschism'? We need a target that does not compile any util scripts. Thx.

[uturuncoglu]

@josephzhang8 Yes, there could be issue in build outside of the UFS Coastal. So, I created this PR to allow testing in your end. It seems that this is already merged but let me know if we need to fix something. If I could reproduce your issue, I think I could fix them.

Thx @uturuncoglu . The most important thing is to add a schism only target so I can try to compile schism alone. After that we'll look into util scripts. Thx

[uturuncoglu]

@josephzhang8 I created an issue in our end - https://github.com/oceanmodeling/schism/issues/1

@platipodium : can u plz help add pschism target? I did not find the entry ... thx

Sorry @josephzhang8 I have no knowledge of CMake, unfortunatly

[josephzhang8]

Actually I saw it in Drive/CMak* but somehow when I

make -j8 pschism

it complained about the target unknow.

[josephzhang8]

@water-e : Hey Eli, maybe you can help. We edited src/CMakeLists.txt in the latest master, but now cannot find the target pschism anymore. Could u plz help? Thx

[platipodium]

It's broken for me, too :=(

[platipodium]

Adding -DBLD_STANDALONE=ON to cmake args gets the target pschism back, thanks @uturuncoglu

-- START: pschism:pschism -- Executable name with this configuration will be pschism_BLD_STANDALONE_TVD-VL

BUT we don't want to impose on the user to set that flag, it should be on by default.

And it should not appear in the exe name ...

[josephzhang8]

I think it's b/c some change in order of compile in src/CM*

[platipodium]

make pschism is still broken on my system

@platipodium We could set it ON by default and set off in coastal model side. So, once the standalone build is working, I could adjust ufs coastal based on it. No problem.
