The feathergui flake contains this hook which sets up paths for scopes. Scopes needs NIX_CFLAGS_COMPILE to contain the -I/nix/store/hash/include/lib paths and LD_LIBRARY_PATH to contain the paths to the .sos for each library to find them.
It's also possible to set up these paths in __env.sc instead of using the above env vars, and potentially generating one of those or suggesting a particular format for it which runs pkg-config would work. This would have the advantage of working with non-Nix build systems. NIX_CFLAGS_COMPILE is not portable.
Maybe it would be better if scopes supported pkg-config more directly in some way?
