I downloaded offline installer file [ 5.12.x Offline Installers, Windows Host, 3.7 GB ]
With your help, I set the path in cmake [ Qt5_DIR flag ], In cmake I pressed the configure and then generate buttons, no problem occurred and everything was done correctly.
i pressed “open project” button and build visual studio project, but show me 631 error!
Where is my mistake?
All errors are from the opencv_world project!
I disabled the BUILD_opencv_world flag in cmake → then build project in Visual Studio, all errors were from the opencv_highgui project. [ 631 error again ]
