It's almost done. But the last step has issues now. Can somebody help? Thanks. It seems libopencv_core3 is the wrong library built? How should I solve it?

Solve it by myself. It is an error of openCV version.
changed it to the following:
find_package(OpenCV 3.0 REQUIRED)

Ref: #13

I had the same issue; your solution solved it. Maybe check in an updated CMakeLists.txt ?
