hiop: raja (dep) build error on +cuda

[balay]

Not directly hiop issue - well raja is a dependency of hiop (also camp - that is triggering raja build failure) - so tagging hiop here.

And the trigger is the change from spack/spack#47720

Log from prior to change:

Notice:

-- Found CUB: /scratch/svcpetsc/spack.a/opt/spack/linux-ubuntu22.04-x86_64/gcc-11.4.0/cuda-11.7.1-nnyolmrglspl7fm2exxhwlhzplopqeuf/include

Log from after the above change:
spack-build-out-bad.txt

Notice:

-- Found CUB: /scratch/svcpetsc/spack.a/opt/spack/linux-ubuntu22.04-x86_64/gcc-11.4.0/cub-2.1.0-jeuemk56wefipunpzgxndxhqusj7ybfj/include

So "reordering" dependencies - reorders the "include" path search - so a different version of cub is found - breaking build.

Perhaps the fix for this issue is to not have such duplicate copies of cub [when both cuda and cub are in dependency graph] - not sure how this can be added to spack.

For now - will work-around with ^raja~cuda
