Add an example that actually uses something from the library

[gnzlbg]

The library in the example project appears to be empty. None of the examples use anything from it.

I'm trying to set this up for a library project and am constantly getting that my library crate cannot be found.

Correct.

Is this using a workspace as you mention in #157? You might need to fiddle with target_rustcflags and add more directories with -L.

Yes.

I tried without any luck. Ended up using rustdoc compile_fail doc tests instead, but I'd prefer to be able to match the error message more precisely using compilefail_rs.
