Are you aware of HIP? It's officially supported and, for code that avoids obscure features of CUDA like inline PTX, it's pretty much a find-and-replace to get a working build:

Don't believe me? Include this at the top of your CUDA code, build with hipcc, and see what happens:

It's incomplete because I'm lazy but you can see most things are just a single #ifdef away in the implementation.
