OpenCV: CUDA_TOOLKIT_ROOT_DIR not found or specified

30 Nov

In the latest OpenCV release version is 2.3.1 (August 2011), if you use CMake to config the build files for VisualStudio, it is likely that you encounter the same error as me:


Some recommend to use the old version 2.3 instead to troubleshoot this, while a simple solution is to point this directory to any existing folder, as shown below:



Now re-click the config button and then re-build, all should be fine!

Happy coding!
