Summary

Add ogre 2.1 dependency to CI systems

Motivation

Some rendering tests are using ogre and we should start switching them to use ogre2. To do this, we need to first add ogre2.1 dependency to our CI systems otherwise the tests will fail with a warning msg about not being able to find the ogre2 render engine.

I believe we have ogre2 in our CI now. Maybe not all platforms have it, but it might be better to open a more acute issue for such platforms.
