Bug#1031189: libogre-dev: Does not automatically derive plugin path

[Matthew Fennell]

Sorry for wasting your time, I think I was wrong to raise this bug and it can be
closed.

I see that /usr/lib/x86_64-linux-gnu/OGRE/cmake/OGREConfig.cmake defines
OGRE_PLUGIN_DIR, and that this path contains a plugins.cfg file that includes
the correct PluginFolder filepath.

Therefore, no magic is required - I simply needed to pass this variable to my
application.

Thanks again for maintaining this package - and thanks also Andreas for
moving on my report to the correct list,
Matthew
