Expected Behavior

I would expect that using (include_subdirs qualified) would not clash with using Menhir in other places than the top-level (which I call “nested” but I'm not sure it is a good word).

Actual Behavior

Dune does not seem to find the module corresponding to the Menhir parser. If I put the (menhir) stanza in a Dune file near the parser (eg. (menhir (module baz))) I get:

File "bar/dune", line 1, characters 0-23:
1 | (menhir
2 |  (modules baz))
Error: I can't determine what library/executable the files produced by this
stanza are part of.

but it doesn't look like there is much I can add to the (menhir) stanza to help it.

Reproduction

• PR with a reproducing test: test: (include_subdirs) qualified and unqualified and nested menhir #7611

Specifications

• Version of dune (output of dune --version): 3.7.1
• Version of ocaml (output of ocamlc --version): 4.14.1
• Operating system (distribution and version): NixOS unstable on x86_64-linux. I use:

  $ nix shell github:nixos/nixpkgs/0a0f9e92d#ocamlPackages.{ocaml,dune_3,findlib}
