'which' looks in native-inputs, not the 'inputs', so this is probably
incorrect when cross-compiling.  I suggest using (search-input-file
inputs "/bin/lilypond") instead.

It is a tool, and not (only?) a library, so do these need to be
propagated, or would some wrapping suffice?

Greetings,
Maxime.
