Question

多次尝试正确编译，但显然我做错了。

我有OpenCV和OpenCVSharp的最新SVN签出。我使用CMake为OpenCV构建我的解决方案（使用x64 Visual Studio 2010配置），然后在Visual C ++ Express 2010中编译它。

之后我再次使用Cmake为OpenCVSharp做一个构建，但是我得到一个错误，说我弄乱了OpenCV dll。

另外，当我第一次在VC ++中打开OpenCV时，我收到一条警告，说它不支持解决方案文件夹。不确定这是否会产生影响。

编译环境：Windows 7 x64

它可能就像你的OpenCV一样简单.dll不在路径中。您没有在帖子中提到过，您是否在编译后设置了路径，以便包含.dll的文件夹？
