Comment 8 for bug 988253

I think you have to check your OpenCV setup/installation again:

file "/usr/local/include/opencv/cvver.h" cannot be read.

does not look like it is ok.

This error happens in the cake module FindOpenCV and it should not look for cvver.h (not contained in OpenCV version 2.x any more) but find and use OpenCVConfig.cmake (the version coding now is at core/version.hpp).

Before running a new build, you should delete the build folder and create it empty again.
