I don't think librespot is maintained anymore. If you try again, maybe give spotifyd a shot. It works well for me in a basic setup (not using Snapcast)

It is maintained at https://github.com/librespot-org/librespot

I don't know why the original author never merged the PRs pointing to the new repo.
