如何在ocamlbuild中包含来自另一个目录的依赖项？

open Ocamlbuild_plugin

let include_other_dir (tags: string list) (path: string) (dep: string) : string =
  let full_path = path ^ "/" ^ dep in
  let new_tags = tags @ ["my_plugin"] in
  let rule = (dep ^ ".native") :: new_tags in
  rule, full_path

let () =
  dispatch begin function
    | After_rules ->
      let path = "<其他目录的路径>" in
      let dep = "<依赖项>" in
      dep |> include_other_dir ["ocaml"; "byte"; "program"] path |> rule
    | _ -> ()
  end

<依赖项>: use_my_plugin

$ ocamlbuild <目标文件>.native
