   2. Set the platform asx64 which is because OpenCV4.3.0 only supportx64

   3. right clickOpenCV → Properties → VC++ Directories

   4. Config include directories: edit include Directories，add directories D:\OpenCV\build\include and D:\OpenCV\build\include\opencv2

      

   5. Config library directories，add D:\OpenCV\build\x64\vc15\lib

      

   6. Go back to OpenCV Property Pages, clickLinker → Input，select Additional Dependencies，edit. Add opencv_world432d.lib from D:\OpenCV\build\x64\vc15\lib
