Example OpenCV sample "calibration.cpp" does not build

I cannot figure out why the calibration.cpp from the doku does not build inside the binary folder. I did set the flag for examples on via ccmake . and what I end up with is the following list. What I want to calibrate my kinect camera from a few chessboard samples I have taken earlier. The file calibration.cpp is existent under opencv/samples/cpp/calibration.cpp. How do I proceed?

calibrate these pictures or can i at all? Because the cv::mat is filled with depth information and not with RGB-Pixels. What sample to use with it? This is an example:

I want to calibrate my kinect camera. The RGB-Images work fine with ./cpp-example-calibration but what do I do with the depth information. How do I calibrate these pictures or can i at all? Because the cv::mat is filled with depth information and not with RGB-Pixels. What sample to use with it? This is an example:
