Problem Building xfeatures2d in OpenCV 3.0

I am trying to transition from OpenCV 2.4.9 to 3.0 but I am having trouble getting xfeatures2d to compile as a lib. I am using VS2012 c++/cli on a Win8.1 64 bit machine using CMake 3.0.1. My system has a NVidia card with CUDA 7.0 installed.

I do not have any problem just making OpenCV 3.0 itself but need to add xfeatures2d so I can use SURF, etc.

I downloaded the xfeatures2d, etc. code from https://github.com/Itseez/opencv_contrib and installed it on my hard drive at the root, so the files are stored in opencv_contrib-master. I added c:/opencv_contrib-master/modules to the OPENCV_EXTRA_MODULES_PATH setting.

Following earlier advice, I have turned off:

BUILD_EXAMPLES 
BUILD_contrib_world,
BUILD_opencv_face, 
BUILD_latentsvm, 
BUILD_line_descriptor, 
BUILD_saliency 
BUILD_world

but changed nothing else. CMake config and master report no problems.

When I now select the ALL_BUILD project, I am still failing. The first project I fail at says:

The next project says:

In total, it reports 105 projects built, and 6 failed.

Any help in getting xfeatures2d to compile so I can use SURF appreciated.

your compiler does not know round . so change that to cvRound

Thanks. Where do I do that? I am using VS2012 which would seem to be the most common development platform.

Thanks. That did allow it to compile but it seems weird that you have to edit the code to get it to compile on the most popular platform. Thanks again for all your help.
