Compiling OpenCV opencv_world with Qt - unresolved externals



I want to compile OpenCV (3.4) with Qt (5.11) (with setting CMake-option WITH_QT and setting Qt5*_DIR paths). The source codes were freshly downloaded from github or Qt-Website. The Solution folder for VC14 is created with the latest CMake.



If I compile it with VC14 (Visual Studio 2015 C++) it perfectly compiles and links the single modules.



But if I also choose the CMake-option BUILD_opencv_world I get unendless (226) linking errors: "unresolved external symbol ...". All of them related to the project opencv_world.



If I remove the CMake-option "WITH_QT" I also can create the opencv_world files.



What do I make wrong?



Below just a the first entries of the error list:
