Are you sure that you've installed OpenCV on your windows device correctly?

Yes.I'm sure.
I extract it and generate in cmake as you said in video.
I think I found the problem.
My Qt Creator is Mingw version.so when I want to select path for system,I select "qt5\5.5\mingw\bin"
However i use opencv in visual studio but i think my path is incorrect.
Do you think this is my problem?
You think if I install Qt visual studio and select path , it will work correctly?
