Error compiling opencv

[pashok2398]

First of all i want to thank you for the work you did here!!!!
I am trying to make the GPU support work, when i compiling using opencv.sh i saw some errors:

CMake Error at modules/dnn/CMakeLists.txt:35 (message):
  DNN: CUDA backend requires CUDA Toolkit.  Please resolve dependency or
  disable OPENCV_DNN_CUDA=OFF

and then

-- Configuring incomplete, errors occurred!
See also "/root/opencv/build/CMakeFiles/CMakeOutput.log".
See also "/root/opencv/build/CMakeFiles/CMakeError.log".

However i wasn't able to find these 2 files in the container....
