Dune: How to add a dependency on one executable to another?

See https://github.com/ocaml/dune/issues/3499 (Allow dependencies for executables).

The work-around I use is to copy the executable and then install the copy. The copying rule adds the dependency. e.g.

ocurrent/ocaml-ci/blob/98057c00918e793142c6b10049df9c522ae29cd1/service/dune

            capnp-rpc-unix
            mirage-crypto-rng.unix
            ocaml_ci
            ocaml-ci-api
            prometheus)
 (preprocess (pps ppx_deriving_yojson)))

; We first build the binaries, then copy them to a new name, then install them.
; This allows us to add in the run-time dependency on ocaml-ci-solver in the
