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:

In total, it reports 105 projects built, and 6 failed.
Any help in getting xfeatures2d to compile so I can use SURF appreciated.
