You can make a plugin which sets these options by putting the following 
lines in a file named myocamlbuild.ml at the root of your project:

--8<----------
open Ocamlbuild_plugin;;

dispatch begin function
   | Before_options ->
       Options.ocaml_cflags := [ "-I"; "+oUnit"];
       Options.ocaml_lflags := [ "-I"; "+oUnit"];
       Options.ocaml_libs := [ "unix"; "oUnit"];
   | _ -> ()
end;;
--8<----------

Then you can just invoke "ocamlbuild test_setup.native".
