The easy part is to add NIX_CFLAGS_COMPILE for "regular" libraries. A bit more tricky is to add the required flags for libclang to find libstdcxx. For this we parse arguments to bindgen to look for -x c++ or -xc++ and if found add NIX_CXXSTDLIB_COMPILE to the arguments. This variable is populated by a complex dance of setupHooks. We trigger this by adding clang to propagatedBuildInputs. A more subtle way may exist.

Bindgen takes a c or c++ header file and turns them into
|
|
rust ffi declarations.
|
|
As with most compiler related software, this will only work
|
|
inside a nix-shell with the required libraries as buildInputs.
