In addition to the widespread practice of prefixing a project name with `lib` to indicate the libraries of that project, in Nixpkgs it's also common to separate headers, libraries, binaries, and documentation into different output attributes of a given [derivation](https://nixos.org/manual/nix/stable/language/derivations.html).

Determining from where to source a dependency is currently a somewhat-involved process: it helps to become familiar with searching the `nixpkgs` source for keywords, in addition to checking discussion platforms like [the official NixOS Discourse](https://discourse.nixos.org).
