The documentation mentions 4 examples (Flocking, Finger Visualizer, Gestures, Motion Visualizer) that should be included in the Examples section of the SDK download package. The link refers to https://developer.leapmotion.com/downloads which redirects to https://developer.leapmotion.com/get-started. I downloaded Leap Motion SDK v2.3.1 for Linux. It contains LeapSDK/samples/Sample.cpp, which is not one of the mentioned examples. Where are they located?
