| V   | CMAKE_CXX_STANDARD_REQUIRED |

| Add | CMAKE_CXX_STANDARD 11 _//Fix undefined reference std:: issue_ |

| X   | OPENCV_ENABLE_ALLOCATOR_STATS _//Fix error:long_ |

| X   | ENABLE_PRECOMPILED_HEADERS  _//Fix math.h issue_ |

| Add | OPENCV_EXTRA_MODULES_PATH where_saved_path_of_opencv_contrib_modules | 

| V   | WITH_OPENNI2 _//for Astra Pro depth camera_ |

| Add | OPENNI2_INCLUDE |

| Add | OPENNI2_LIBRARY |
