Downstream projects require ogre-dev

[cottsay]

It looks like the rviz headers reference ogre header files in https://github.com/ros-visualization/rviz/blob/hydro-devel/src/rviz/ogre_helpers/qt_ogre_render_window.h#L36-L37

This means that downstream projects need ogre-dev to build (namely librviz_tutorial).

Either rviz should run depend on ogre-dev or the downstream project(s) should build depend on ogre-dev

This may actually run deeper than I thought. I added ogre-dev to the build deps for librviz_tutorial, so it was installed, but it still failed to find the ogre headers.

In Fedora, they are in /usr/include/OGRE/ -- are they somewhere else on Ubuntu?

Looks like rviz_plugin_tutorials has the same issue
