CMake failing for gnugpu on Perlmutter-GPU

[xylar]

When I run:

module load cmake

mkdir -p build_omega/build_pm-gpu_gnugpu
cd build_omega/build_pm-gpu_gnugpu

export METIS_ROOT=/pscratch/sd/x/xylar/spack_pm-gpu_test//dev_polaris_0_3_0_gnugpu_mpich/var/spack/environments/dev_polaris_0_3_0_gnugpu_mpich/.spack-env/view
export PARMETIS_ROOT=/pscratch/sd/x/xylar/spack_pm-gpu_test//dev_polaris_0_3_0_gnugpu_mpich/var/spack/environments/dev_polaris_0_3_0_gnugpu_mpich/.spack-env/view

cmake \
   -DOMEGA_BUILD_TYPE=Release \
   -DOMEGA_CIME_COMPILER=gnugpu \
   -DOMEGA_CIME_MACHINE=pm-gpu \
   -DOMEGA_METIS_ROOT=${METIS_ROOT}\
   -DOMEGA_PARMETIS_ROOT=${PARMETIS_ROOT}\
   -DOMEGA_BUILD_TEST=ON \
   -S /global/u2/x/xylar/e3sm_work/polaris/add-omega-ctest-util/e3sm_submodules/Omega/components/omega/ \
   -B . 

I'm seeing:
