OpenCV 3.0视频3.0错误

我尝试用CMake 3.1.0为Qt Creator 5.4编译OpenCV 3.0 alpha库，但出现了错误：

CMAKE --> CMAKE_BUILD_TYPE = Debug
WITH --> WITH_EIGEN = 0
WITH --> WITH_OPENGL = 0
WITH --> WITH_IPP = 0其余设置为默认设置。我的操作系统是64位Windows 7。OpenCV库来源：http://sourceforge.net/projects/opencvlibrary/files/opencv-win/3.0.0-alpha/
怎么啦？有什么想法吗？

当我在windows上用mingw编译opencv3.0.0时也遇到了同样的问题。我根据这个link找到了一个解决方案。
进入opencv源代码所在的存储库中。
对我来说，它是"C:/opencv/sources/“。
转到"Cmake/“文件夹并搜索名为"OpenCVCompilerOptions.cmake”的文件。
您只需注释这行代码：
add_extra_compiler_option(-Werror=non-virtual-dtor)所以它应该变成
#add_extra_compiler_option(-Werror=non-virtual-dtor)现在，您已经可以使用cmake配置和生成makefile了，mingw32-make命令行应该可以正常工作了。
