错误一 [modulescoreCMakeFilesopencv_core.dirbuild.make:1494: modules/core/CMakeFiles/opencv_core.dir/vs_version.rc.obj] Error 1
将CMake中的 OPENCV/OPENCV_ENABLE_ALLOCATOR_STATS 不打勾
错误二 [modulescoreCMakeFilesopencv_core.dirbuild.make:1708: bin/libopencv_core450.dll] Error 1
设置OPENCV_VS_VERSIONINFO_SKIP=1，也就是打勾，若无法找到变量OPENCV_VS_VERSIONINFO_SKIP，则可以自己添加一个：
错误三 CMake Error: CMake was unable to find a build program corresponding to "MinGW Makefiles". CMAKE_MAK将CMAKE_MAKE_PROGRAM项后面的路径设置为Qt安装路径下的路径如下所示：MinGW/bin/mingw32-make.exe，重新点击Configure
错误四 windres.exe: unknown option -- W将“ENABLE_PRECOMPILED_HEADERS”取消
错误五 in the file opencv/sources/modules/videoio/src/cap_dshow.cpp, you have the following error : 'sprintf_instead_use_StringCbPrintfA_or_StringCchPrintfA' was not declared in this scope ...解决：opencvsourcemodulesvideoiosrccap_dshow.cpp中，在#include “DShow.h“上一行中插入: #define NO_DSHOW_STRSAFE
