Maybe a comment would be helpful to remember that answer. :-)

Elsewhere, we use:

--8<---------------cut here---------------start------------->8---
    (inputs
     (list ;; XXX: We can't simply #:use-module due to a cycle somewhere.
           (module-ref
            (resolve-interface '(gnu packages engineering))
            'cgns)
           cli11
[...]           
--8<---------------cut here---------------end--------------->8---

see paraview-5.9, d-tools, make-autoconf-wrapper, etc.
