Comment 1 for bug 1678091

It's very odd that you had the pkg-config files for OpenCV without having the OpenCV development package installed. This is likely an issue with the OpenCV packages.

However, there really isn't much purpose in building Panda with OpenCV support now that we support Video4Linux for webcam capture. To people who run into this issue, I would suggest building with --no-opencv to be sure. In the future, I will probably simply disable it by default to avoid issues like this.
