The comment on chief Delphi also had a missing return character. Could you add that here?

The other failure mode is a vendor dependency, pulling in something stupid. Should we mention that?

Perhaps something about how the versions need to match, not just about they need to be upgraded?

Something like
upgrade photonlib, wpilib, and other vendordeps?

I wouldn't bother unless you can think of a vendor which does, it would only lead people down the wrong path right now.

Versions needing to match is difficult, we often have mismatching versions. If they are both latest it should work.

C++ already has this

There should be an explanation on the dependencies task. I don’t think it’s obvious what you’re supposed to do with it. It should be reworded to say that you need to look through the output and see if there’s an old version of OpenCV being pulled in (same goes for WPILib).
