編譯opencv3.1.0時出現錯誤：error: ‘NppiGraphcutState’ has not been declared

安裝cuda之後再安裝opencv時出現錯誤：
/data/opencv-2.4.11/modules/gpu/src/graphcuts.cpp:120:54: error: ‘NppiGraphcutState’ has not been declared
typedef NppStatus (*init_func_t)(NppiSize oSize, NppiGraphcutState** ppStat
^
/data/opencv-2.4.11/modules/gpu/src/graphcuts.cpp:135:18: error: ‘NppiGraphcutState’ does not name a type
operator NppiGraphcutState*()
^
/data/opencv-2.4.11/modules/gpu/src/graphcuts.cpp:141:9: error: ‘NppiGraphcutState’ does not name a type
NppiGraphcutState* pState;
cuda8.0較新，opencv-2.4.11較早，要編譯通過需要修改原始碼：
修改/data/opencv-2.4.11/modules/gpu/src/graphcuts.cpp
將
#if!defined(HAVE_CUDA)||defined(CUDA_DISABLER)
改為
#if!defined(HAVE_CUDA)||defined(CUDA_DISABLER)||(CUDART_VERSION>=8000)
重新編譯即可。
