This was introduced in #816. I commented there as well.

@jbrookshire: a PR would resolve this sooner I think.

What is a bit of a mystery is why the user reporting this in the ROS Answers question only runs into this with OpenCV3.

Yes, I had the error with all plain cmake packages (for me: octomap, opencv, and orocos)

This is clearly a bug in the patch adding Ninja support. Thank you for reporting this. I created #827 to fix the logic and will do a patch release.
