Ogre exception duplicated resource name

[phil0stine]

This applies to a non-standard configuration (Ogre 1.10 on OSX and rviz branch osx_ogre_1_9), but it seems like it might apply more broadly so I am reporting.

After successful compilation, running rviz gives the error:

OGRE EXCEPTION(4:ItemIdentityException): Resource with the name rviz/glsl120/include/pass_depth.vert already exists. in ResourceManager::add at /tmp/ogre/OgreMain/src/OgreResourceManager.cpp (line 168)

Looking at the GLSL .program files, there do appear to be 2 instances of the same name, rviz/glsl120/include/pass_depth.vert, in
glsl120 and gsl120/nogp.

My naive workaround was to rename the resource in glsl120/nogp to be rviz/glsl120/nogp/pass_depth.vert, which resolved the exception and rviz seems to be working fine.

Can you open a pull request to this effect. It sounds like a worthwhile change.

I'm still seeing this error despite recompiling after applying #1063. My OGRE version is 1.10.11 (Xalafu), and I'm using an older rviz (version 1.11.8 on indigo). The exact error I get is:

[ERROR] [1524151129.545731714]: ItemIdentityException: Resource with the name rviz/glsl120/include/pass_depth.vert already exists. in ResourceManager::add at /home/vecna/ogre-ws/ogre-1.10.11/OgreMain/src/OgreResourceManager.cpp (line 158)

Aborted (core dumped)

I have built my OGRE and rviz from source with the stereo flags on. I use this command to compile rviz:
PKG_CONFIG_PATH=/path/to/ogre-installation/lib/pkgconfig:${PKG_CONFIG_PATH} catkin_make --cmake-args -DCMAKE_SHARED_LINKER_FLAGS:STRING=" -Wl,-rpath,/path/to/ogre-installation/lib" -DCMAKE_CXX_FLAGS:STRING="-DOGRE_STEREO_ENABLE=1" -DUseQt5:BOOL="0"
as mentioned in this tutorial.
Any ideas about how I could resolve this would be much appreciated!

Fixed via #1063.
