OpenCV 3.1 cmake error during configuration

edit

Hy,

configuring OpenCV 3.1 for an Tegra TX1 Ubuntu 16.04 with CUDA 8.0 lead me to the following error:

    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:
CUDA_CUDA_LIBRARY (ADVANCED)
    linked by target "example_gpu_alpha_comp" in directory /home/aa/Desktop/OPENCV_INSTALL/opencv/samples/gpu
    linked by target "example_gpu_bgfg_segm" in directory /home/aa/Desktop/OPENCV_INSTALL/opencv/samples/gpu
    linked by target "example_gpu_cascadeclassifier" in directory /home/aa/Desktop/OPENCV_INSTALL/opencv/samples/gpu
   ... and so on

For the installation process I am following this guide. Anyway all errors are related to "example_gpu_SomeExampleName". I googled it up and found out that people having similar problems since CUDA only comes with x64 libraries. How to work around this issue? Is it possible to configure OpenCv 3.1 for Ubuntu only in x64 mode? Any help would be appreciated.

EDIT 1: added CMakeError.log & CMakeOutput.log
