spurious failure with hidden libraries

[avsm]

When using hidden libraries (as in https://github.com/mirage/ocaml-cf) that are only enabled on some switches (such as system = macos), opam-dune-lint throws up spurious failures that cannot be fixed in ocaml-ci:

File "lib_gen/dune", line 54, characters 27-41:
54 |  (modules bindgen bindings types_detected))
                                ^^^^^^^^^^^^^^
Error: Module Types_detected doesn't exist.
opam-dune-lint: internal error, uncaught exception:
                (Failure
                  "run ['dune' 'describe' '--format=csexp' '--lang=0.1']: exited with 1")

This seems to be a dune bug:

$ git clone https://github.com/mirage/ocaml-cf.git
$ dune describe
File "lib_gen/dune", line 54, characters 27-41:
54 |  (modules bindgen bindings types_detected))
                                ^^^^^^^^^^^^^^
Error: Module Types_detected doesn't exist.

This issue has been fixed since opam-dune-lint did not use dune decribe command.
There's now an issue(ocaml/dune#10779) opened in Dune that related.
