Hello,
The system I use is Windows 8 with Nvidia Geforce GT 640M LE. The version of Visual Studio is 2013, Opencv is 2.4.9, and the Cuda's version is 6.5. I followed this tutorial : https://initialneil.wordpress.com/2014/09/25/opencv-2-4-9-cuda-6-5-visual-studio-2013/ I did all steps like he did, but i dont get an error in debug mode (I ignored), and Cmake gave me some warnings like -Target "..." links to itself or -CMAke Warning (dev) at ...: Policy CMP0038 is not set:... So I went on and included the install folder in my Visual Project. But there was an error that Visual told me no CUDA support. So I dont know why. I did all Steps in the Tutorial.
Please help me.
