Opencv_world451.dll missing in x86 build

I’m upgrading my Visual Studio v15 C++ project from openCV v3.4.3 to v4.5.1 in x86 configuration. I built it in CMake and then ran BUILD and INSTALL in OpenCV.sln in the Visual Studio. But I cannot find the opencv_world451.dll anywhere. It’s supposed to be in …\install\x86\vc15\bin but it’s just not there. There are bunch of other dll files, but not the opencv_world451.dll. Could anyone help?

Hi Eugene,
Maybe you forgot to check BUILD_opencv_world entry in the cmake file. By default its unchecked. It’s under the BUILD group, if you enable the grouped view on cmake GUI. You should tick the checkbox to produce opencv_worldxxx.dll.
