CUDA library not found when compiling #14

Closed olayasturias closed 7 years ago

OpenCV version: 3.0.0 O.S. : Ubuntu 14.04 CUDA toolkit installed but without NVIDIA driver

When compiling OpenCV 3.0.0 branch, the configure step fails with:

CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:

Seems like it didn't found the libcuda.so

Solved by adding the following cmake flag: -DCMAKE_LIBRARY_PATH=/usr/local/cuda/lib64/stubs

It looks like its your first issue, but good job!

Fix documented here.

Let me know in case I need to add any additional steps that you might have done.
