compiling Gazebo with Ogre installed locally

I'm trying to compile Gazebo with a local install of Ogre. I have the Ogre .pc files pointing to the right locations. However, the Find Ogre bit in the [SearchForStuff.cmake](https://bitbucket.org/osrf/gazebo/src/14a3e6e94163602588f6965f6123f4f777e2e302/cmake/SearchForStuff.cmake?at=default&fileviewer=file-view-default) file still seems to be looking at default /usr/include/OGRE Is there a configuration variable I am missing - I couldn't find anything for Ogre. Thank you
