Please clean-up the build dir, run CMake and provide the full CMake output together with the full CMake invocation command line here for analysis.

Something wrong with your build system. It uses header files from different locations.

For example opencv2/nonfree/gpu.hpp is used from

/ debug/src/OpenCV2.4.5/modules/nonfree/include/opencv2/nonfree/gpu.hpp

but opencv2/gpu/gpu.hpp is used from

/ debug/include/opencv2/gpu/gpu.hpp

It must be used from

/ debug/src/OpenCV2.4.5/modules/gpu/include/opencv2/gpu/gpu.hpp
