any way to build ESMF for UFS_UTILS with less options?

[edwardhartnett]

NetCDF gives us options like --disable-utilities, which allow for a faster compile of the lbrary in CI.

Does ESMF have anything similar? Anything we can turn off in the build to save time, but still provide everything UFS_UTILS needs?

@GeorgeGayno-NOAA do you know?

@edwardhartnett I do not know. Perhaps @theurich can advise.

You can set ESMF_MOAB=OFF to turn off building MOAB. This portion of the code is not yet used internally by default, and I doubt that UFS_UTILS is making the required run-time call to use it.
The only other part that might have some significant savings is to set ESMF_ARRAY_LITE=TRUE. This reduces the the overloading of Array and Field classes to only up to 4D, which might be sufficient for UFS_UTILS, also.
Obviously, using an external PIO via ESMF_PIO=external will safe you the time of internally building it, but I assume you are already doing that.
Those are the lowest hanging fruit I can think at the moment.
