OK so I missed the OpenMP vs OpenMPI with incorrectly setting
-DOpenMP_libomp_LIBRARY="/path/to/openmpi-4.1.1_ucx_cuda_11.0.3_support/lib//libompitrace.so.40.30.0
So
I changed it to point to /cm/local/apps/gcc/10.2.0/lib/libgomp.so.1.0.0
-- Found PETSc 3.18.0
CMake Error at
/path/to/cmake/cmake-3.22.1-linux-x86_64/share/cmake-3.22/Modules/FindPackageHandleStandardArgs.cmake:230
(message):

Perhaps I need to reach out to the richdem
