There is many solutions and you get one of them.

1/ Comand line solutions

1.1/ Using ocamlfind:

Since it's an ocamlfind package you can use it.

ocamlbuild -ocamlc "ocamlfind ocamlc -package ounit" -lfags -linkpkg
-lib unix test_list.byte

1.2/ Using the library directly (like you did).

2/ Shell script/Makefile solution

Put all your stuffs form the previous solutions in a shell script or a Makefile.

3/ A solution with an Ocamlbuild plugin:

$ cat _tags
"test_list.byte": use_unix

$ cat myocamlbuild.ml
open Ocamlbuild_plugin;;
open Command;;

let packages = "ounit" (* "pkg1,pkg2,..." *);;

let ocamlfind cmd =
  S[A"ocamlfind"; A cmd; A"-package"; A packages];;

flag ["ocaml"; "link"] (A"-linkpkg");;

dispatch begin function
  | After_options ->
      Options.ocamlc := ocamlfind "ocamlc";
      Options.ocamlopt := ocamlfind "ocamlopt";
  | _ -> ()
end

$ ocamlbuild test_list.byte
