Hi,  
Did you install [cudnn](https://developer.nvidia.com/cudnn)?

Yes ,I did. I can configure successfully, but without the following file, am I wrong? Can I download files directly  
The file are **cudaarithm.hpp** , **cudaimgproc.hpp**. **cudafilters.hpp**. **cudafeatures2d.hpp**. **cudaobjdetect.hpp**

That’s regular opencv file.  
delete cmakecache.txt and rerun cmake and post full output
