OpenMP not actually required?

[marchdf]

Bug description
If building for C++ (BUILD_OPENFAST_CPP_API), then FIND_PACKAGE requires that it finds OpenMP (https://github.com/OpenFAST/openfast/blob/main/CMakeLists.txt#L114). That will fail if openmp is not found but strictly speaking openmp should not be required when building the API. Further checks, check that it actually found OpenMP but the REQUIRED keyword does not actually let the code get to them.

To Reproduce
Build the CPP API on machine that does not have openmp and with the default option(OPENMP "Enable OpenMP support" off).

Expected behavior
Described above

Screenshots, if applicable
NA
OpenFAST Version
3.5.2
