Using Kinect and other OpenNI compatible depth sensors?

edit

I am going to connect Kinect and want to run the code "openni_capture.cpp". However I can not understand the following configuration:

"If one or both products were installed to the other folders, the user should change corresponding CMake variables OPENNI_LIB_DIR, OPENNI_INCLUDE_DIR or/and OPENNI_PRIME_SENSOR_MODULE_BIN_DIR. Configure OpenCV with OpenNI support by setting WITH_OPENNI flag in CMake."

How can I configure CMake variables OPENNI_LIB_DIR, OPENNI_INCLUDE_DIR or/and OPENNI_PRIME_SENSOR_MODULE_BIN_DIR?

N. B. I installed opencv, openni, nite, PrimeSensor. Would you explain please?
