#TIL #clangd (the #LSP) doesn't seem to find system libraries if the path is not explicitly added to #clang (the compiler).

So here I am unnecessarily sprinkling `-I/usr/local/include` everywhere.

On a similar note, on macOS, the runtime doesn't seem to find dynamic libraries stored in `/usr/local/lib`, so you need to manually add that to the `@rpath` (which I didn't even know existed until now).
