3.1 samples CUDA, compiling with CUDA

edit

Hello, I have just started using OpenCV 3.1 (not the contrib branch) and haven't really kept up with OpenCv for a year or more. Now I have built and installed with CUDA:

 Device 0: "GeForce GTX 950M"
 CUDA Driver Version / Runtime Version          7.50 / 7.50

 Device supports Unified Addressing (UVA):      Yes
 Device PCI Bus ID / PCI location ID:           1 / 0
 Compute Mode:
     Default (multiple host threads can use ::cudaSetDevice() with device simultaneously) `
deviceQuery, CUDA Driver = CUDART, CUDA Driver Version  = 7.50, CUDA Runtime Version = 7.50, NumDevs = 1

Unfortunately, many error related to using the GPU occur:

Are there dependencies for the samples in /bin? (i.e. caltech images)

opencv_test_cudaarithm :

[----------] 8 tests from CUDA_ImgProc/Demosaicing
[ RUN      ] CUDA_ImgProc/Demosaicing.BayerBG2BGR/0

  Actual: true
Expected: false

Similarly

./opencv_test_cudaobjdetect
CTEST_FULL_OUTPUT

I have had to sudo cp libippicv.a /usr/local/lib/ in order to make a simple cuda_test.cpp:

CFLAGS = `pkg-config --cflags opencv`
LIBS = `pkg-config --libs opencv`
INC = -I/usr/local/cuda-7.5/targets/x86_64-linux/include

% : %.cpp
    g++ $(INC) $(CFLAGS) $(LIBS) -o $@ $<

But this still resulted in a large number of errors:
