Error compiling against Yojson

I have import for Yojson in my code

open Yojson.Basic.Util

and following in Make file

eval `opam config env` && ocamlbuild -use-ocamlfind voigt.native

I'm getting error "Unbound module Yojson", while compiling 

eval `opam config env` && ocamlbuild -use-ocamlfind voigt.native
ocamlfind ocamlopt -c -o config.cmx config.ml
+ ocamlfind ocamlopt -c -o config.cmx config.ml
File "config.ml", line 1, characters 5-22:
Error: Unbound module Yojson
Command exited with code 2.

When I use utop everything works. What should I do to correct this error?

You need to specify, that you want to use yojson. Assuming, that the package name is yojson the correct command would be:

ocamlbuild -use-ocamlfind -pkg yojson voigt.native

And on modern installations you even do not require to use -use-ocamlfind flag, as it should work even without this.
