If we can fix the cmake to correctly work in the NixOS env, I'd rather do that than use a script to edit the cmake config. If I can use find_library and then fall back to building the included version, would that work?

I'm 100% with you on this. NixOS is a little special, so we often have to work around things but it's *BY FAR* preferable to have proper support upstream. That being said, it looks like NixOS will be the first distribution to start carrying your work!

Yep, that sounds like the way to go. Just FYI, on latest master (2146ead), I still need to use my CMakeLists.txt and the manual install you can see in the installPhase part.

How does the hidapi.h header get found with your changes? The cmake edits you make don't make that clear to me. Is it in /usr/include?

I'm not a cmake guru at all, but I guess that find_library uses pkgconfig to locate the include files.
