I don't know how to use OpenMP properly...
In opensubdiv-3.5.0, OpenMP is used since NO_OMP was dropped.
( https://cgit.freebsd.org/ports/commit/graphics/opensubdiv?id=161039e32b880280cc0fb7b478bfc2a0181ba8fc )
Therefore, -fopenmp=libomp is added to all compilations.
However, when linking libraries, it may be necessary to link some kind of openmp library, but there is no writing about it anywhere. (something like ${OpenMP_CXX_LIBRARIES})
So I think that if NO_OMP is not written in CMAKE_ON, it will generate a library that cannot be used.
This is just a guess by me, not understanding OpenMP :)
