Build against both ogre 1.12 and 1.10

[traversaro]

This will probably be necessary in any case to install gazebo in a ros2 environement with rviz2 installed. However, my main interest right now is to debug the ogre 1.12 build of conda-forge (for RoboStack/ros-galactic#24), as I already had experience in using Gazebo with Ogre 1.12 built via vcpkg, so it is more familiar for me to debug any problem here.

I tried to use track_features to de-prioritize ogre 1.12, but I am not sure if this actually works, but I gave it a shot.

Hi! This is the friendly automated conda-forge-webservice.
I tried to rerender for you, but it looks like there was nothing to do.

I suspect all the failure are unrelated to the actual PR and related to conda-forge/qwt-feedstock#28 . Let's try with a clean build.

The track_features aspect seems to work, if I install conda create -n gazebo gazebo or mamba create -n gazebo gazebo I get the ogre 1.10 version, but with conda create -n gazebo gazebo ogre=1.12 or mamba create -n gazebo gazebo ogre 1.12 I get the ogre 1.12 version.
