you will need the opencv_contrib repo (see readme there for build instructions)

if you want to stick with outdated opencv3.0.0 or 3.1.0, please make sure to check out exactly the same revision you're using in opencv_contrib, otherwise it's probably the better idea, to update your main opencv repo to latest master before trying to build with the contrib modules
