cd opencv-4.4.0
mkdir bulid
cd bulid

 

4. cmake

cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D WITH_TBB=OFF -D WITH_IPP=OFF -D WITH_1394=OFF -D BUILD_WITH_DEBUG_INFO=OFF -D BUILD_DOCS=OFF -D INSTALL_C_EXAMPLES=ON -D INSTALL_PYTHON_EXAMPLES=ON -D BUILD_EXAMPLES=OFF -D BUILD_PACKAGE=OFF -D BUILD_TESTS=OFF -D BUILD_PERF_TESTS=OFF -D WITH_QT=OFF -D WITH_GTK=ON -D WITH_OPENGL=ON -D BUILD_opencv_python3=ON -D OPENCV_EXTRA_MODULES_PATH=../../opencv_contrib-4.4.0/modules -D WITH_V4L=ON  -D WITH_FFMPEG=ON -D WITH_XINE=ON -D OPENCV_ENABLE_NONFREE=ON -D BUILD_NEW_PYTHON_SUPPORT=ON -D OPENCV_SKIP_PYTHON_LOADER=ON -D OPENCV_GENERATE_PKGCONFIG=ON ../
