Custom Setups don't work

[lally]

Hi, this is a post-to-the-right-project move of input-output-hk/stack2nix#170 -- I had a stack project that used proto-lens-protoc, and there are both haskell packages and top-level nix packages for this.

I frankly don't care if the solution is hacky, but what's the simplest (to do now, to keep working later) method of getting my proto's sorted for my package? The custom setup used /just/ generates haskell from the .proto files. So any invocation of the protoc compiler that results in the files being in a place that's accessible (and not in my src/ directory, where version control's an issue) for compilation is fine by me.

Ugh, this is still probably the wrong place, looking around more. I'll retry on haskell.nix.
