Problem of building OpenCV 2.4.5 with Cuda 5.5 RC

When I use cmake to configure, it will it cannot found CUDA_npp_LIBRARY

CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:
CUDA_npp_LIBRARY (ADVANCED)
    linked by target "opencv_core" in directory /home/gianluigi/Lib/opencv-2.4.5/modules/core
    linked by target "opencv_gpu" in directory /home/gianluigi/Lib/opencv-2.4.5/modules/gpu
    linked by target "opencv_nonfree" in directory /home/gianluigi/Lib/opencv-2.4.5/modules/nonfree

I think this is caused by NVIDIA split the libnpp to libnppc, libnppi and libnpps in CUDA 5.5. Is there any way to fix this problem?

NVIDIA divide npp into 3 libraries.

libnppc.so is general libnppi.so is for image processing libnpps.so is for signal processing

So, just a hack for now open your CMakeCache.txt and manually set it to your path. Like following //"npp" library CUDA_npp_LIBRARY:FILEPATH=/opt/cuda/lib64/libnppc.so;/opt/cuda/lib64/libnppi.so

I guess it'll be fixed in next version of cmake. Anyway we should workaround it in OpenCV.

Sorry, it can configure now, but it appear many error when I build it. Like, error: calling a __device__ function("AddMat") from a __host__ function("addMat") is not allowed detected during instantiation of "void arithm::addMat<T,D>(cv::gpu::PtrStepSzb, cv::gpu::PtrStepSzb, cv::gpu::PtrStepSzb, cv::gpu::PtrStepb, cudaStream_t) [with T=ushort, D=double]"

Compilation issues with CUDA 5.5 will be fixed in 2.4 branch and in the next release (2.4.6).

OpenCV 2.4.5 can be built only with CUDA 4.2 or 5.0.
