[CRAZYFLIE + LEAP MOTION] Image attached I need help in integrating these two devices wherein I will be able to control the CrazyFlie 2.0 with a Leap Motion Controller. As of now, I'm stuck with the importing of libraries. Whenever I open the CrazyFlie PC Client, it says "Leap Motion libraries probably not installed" but I already have the Leap SDK, I just don't know where to put it. I believe the python code below is the leapmotion interface used for the CrazyFlie PC Client. Any help is much appreciated. Many thanks!
