     Configure OpenCV with Intel Perceptual Computing SDK support by setting ``WITH_INTELPERC`` flag in CMake. If Intel Perceptual Computing SDK is found in install folders OpenCV will be built with Intel Perceptual Computing SDK library (see a status ``INTELPERC`` in CMake log). If CMake process doesn't find Intel Perceptual Computing SDK installation folder automatically, the user should change corresponding CMake variables ``INTELPERC_LIB_DIR`` and ``INTELPERC_INCLUDE_DIR`` to the proper value.
