we don't need anything about shogun in this first test we just want to have a sanity test that proves opencv was included in the build. We also use assertions in tests not prints.

Since this test isn't testing anything probably just create a opencv data structure and that is it. I don't know/remember that much about testing in c++ is it cool to have a test that would fail by throwing a missing link exception or can we do something like `assert_nothing_raised` (thats the ruby in me lol) ping @iglesias
