[chapulina]

🎉 New feature

Summary

Porting #126 to Dome. Also added ign-rendering to the list of conda packages from Dome.

@mabelzhang , do you think you could give it a look?

Test it

I recommend using meld to see the diff between citadel and dome:

meld citadel dome

I removed the caveats for ign-cmake because they're not needed anymore since gazebosim/gz-cmake#154.

ign-rendering Conda package worked for me:

>conda search libignition-rendering4 --channel conda-forge --info
>conda install libignition-rendering4 --channel conda-forge

colcon instructions for source install worked as well.

Do we need to update the per-library tutorial for ign-rendering?
