I don't know Cmake, so I can't do a meaningful review of most of the change. But I did spot what looks like several incorrect compiler arguments.

Can everyone please re-review, I've made some updates.

Looks good to me now. I'll do some sanity checks with my preexisting scripts to see if all's good.

Hang on, my scripts no longer set the CUDA host compiler correctly (and I'm passing it via env variable CXX). Don't merge while I investigate.

I really dislike the pattern of changing the compiler variables programmatically for the reasons mentioned inline. But since we already do that, I wouldn't hold this PR up over it, we can address that later in the eventual CMake refactor.

The other suggestion about the arch option is a "nice to know" low priority QOL change that can be skipped for now. I assume most of these hacks are temporary until we get proper CMake support for Feta, so if it works for feta and doesn't break existing usecases, I'm ok with merging.

Until CMake has first class support for Feta, we probably can't avoid this.

We need to only take this branch if the device backend is CUDA.

* Add rudimentary CMake support for Feta.
a2a85bf 
* Refactor RDC handling to not create separate explicit targets.
* Drive-by: Don't use the NVCC version of `normal_distribution_base` for
  Feta because it uses `erfcinv`, a non-standard function that Feta doesn't
  have.
