Open CMake, configure the source code path of opencv and the path to generate the vs project, and click "Configure".
Click "finish" to start the first configuration work.
After the first configuration is complete, check BUILD_opencv_world.
Add the modules module path in opencv_contrib in OPENCV_EXTRA_MODULES_PATH.
