How to build erlang dependency with rebar and make at once in Elixir project

Question

I wrote a erlport wrapper for elixir, but have a problem to compile erlport as a dependency. You can find it here: https://github.com/fazibear/export

Export mix.exs file:

defp deps do
  [
    {:erlport, git: "https://github.com/hdima/erlport.git", compile: "rebar compile && make"},
    {:ex_doc, "~> 0.11", only: :dev},
    {:earmark, ">= 0.0.0", only: :dev}
  ]
end

And another project that uses this package. When I add a package to this project like this:

defp deps do
  [
    {:export, path: "/Users/bla/dev/export"}
  ]
end

and invoke mix compile it runs just fine. Erlport compiles correctly with rebar and make.

Problem starts when I try to add project from hex.

defp deps do
  [
    {:export, "~> 0.0.6"}
  ]
end

Elport wont compile. As you can see in latest commits I tried a few combinations of manager and compile parameter in export mix file, but nothing works.

How can I compile this lib dependency ?

Thanks.

Hex manual

It seems, that just having rebar config file in dependency should work out of the box. Also, remember that for runtime dependencies you also need to add them to applications, not only deps.
