Hit with "clang-11: error: Unsupported CUDA gpu architecture: gfx900:xnack-" while making examples

I want to build the examples and I'm following the instructions in the README and my error message is below.
Seems closest to issue #116 where use of "-x hip" resolved it, but I need help on where to make the change.
