常用配置：
WITH_OPENGL=ON
DBUILD_opencv_rgbd=OFF #此項需要關閉，不然編譯opencv_contrib時會報錯
OPENCV_GENERATE_SETUPVARS=OFF
OPENCV_EXTRA_MODULES_PATH=your path #這里填寫opencv_contrib/modules的路徑
編譯時報錯：

需要額外添加兩條配置
DOPENCV_SKIP_LIBATOMIC_COMPILER_CHECK=ON
DOPENCV_ALLOCATOR_STATS_COUNTER_TYPE=int64_t
OPENCV_ENABLE_ALLOCATOR_STATS=OFF
DOPENCV_ALLOCATOR_STATS_COUNTER_TYPE
