使用OpenCV 3.3.0
使用Visual Studio 2017，我尝试运行我的代码，没有发现错误。 总是说“应用程序无法正确启动（0xc000007b）”（已翻译）。
已经在调试文件夹中有这个dll文件：
这是我的代码：

我在编译lib时出错！
source code设置为opencv文件夹； build the binaries设置为一个空文件夹，然后将其configure设置为OPENCV_ENABLE_NONFREE并进行检查，也搜索
OPENCV_EXTRA_MODULES_PATH并将路径设置为modules文件夹
已提取的opencv-contrib内部； configure，然后打generate，最后打open project；
