(note: I am not sure the use case below is supposed to be supported, as the documentation states that build info can be embedded in executables, but does not explicitly mention whether it can be embedded in libraries.)

Expected Behavior

Define a library depending on dune-build-info and have a ppx rewriter depending on said library.

Actual Behavior

Dune fails with:

File ".ppx/98cd9c27bc47def1a842c7a721af4e6b/_ppx.ml", line 1:
Error: No implementations provided for the following modules:
         Build_info__Build_info_data referenced from /Users/xclerc/.opam/4.10.0/lib/dune-build-info/build_info.cmxa(Build_info)
