Hi!
I’d like to test a project on all 3 platforms, and some dependencies need to be installed from Chocolatey. I think it would be great to make this work very similar to this: https://docs.travis-ci.com/user/installing-dependencies/#installing-dependencies-on-multiple-operating-systems without having to resort to any kind of manual branching (to only try to run choco on windows) on the platform envvar.
Is this planned? Perhaps it already works, just isn’t documented? 
P.S.: Yes, this was inspired by Snap Addon Similar to apt addon available?
