It might work for the OpenMP invocations, but hard to tell for me on a system with CUDA installed. As it's a `.cu` test after all, I think I would prefer the uniformity of passing `--cuda-path` everywhere and be safe from any weird interaction.

Might need `-nogpulib -nogpuinc` in those cases, we do that in other `.cu` files in the test suite.
