For this guide, the focus is on using the git repositories. This is because the 3.1.0 version of OpenCV will not build with CUDA 8.0 without applying a small upstream change from the git repository.

If you are building OpenCV with CUDA 8.0, you must execute one additional git command. This is to apply a fix for building specifically with the 8.0 version of CUDA that was not part of the 3.1.0 release. To do this, use the "git cherry-pick" command: There are some upstream changes that must be applied via the `git cherry-pick` command. The first of these is to apply a fix for building specifically with the 8.0 version of CUDA that was not part of the 3.1.0 release:

This step is not needed if you are building with CUDA 7.0 or 7.5. Secondly, there is a fix for a CMake macro call that is problematic on some systems:
$ git cherry pick cdb9c

The last upstream fix that is needed deals with the `pkg-config` configuration file that is bundled with the developer package (`libopencv-dev`):
$ git cherry-pick 24dbb

At this point, the `opencv` repository is ready for building.
