WITH_CUDA 勾選上 使得OpenCV支持GPU加速
需要利用CMake自編譯
相關軟件： OpenCV3.0 CUDA8.0 VS2013 64位 Win10
問題描述：
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_cufft_LIBRARY (ADVANCED) (ADVANCED)
CUDA_nppi_LIBRARY (ADVANCED) (ADVANCED)
CUDA_nppc_LIBRARY (ADVANCED) (ADVANCED)
CUDA_npps_LIBRARY (ADVANCED) (ADVANCED)
......
解決方案
查看C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v8.0\lib\x64安裝目錄下cufft.lib，nppi.lib, nppc.lib npps.lib等庫是否存在
注意：
# In CUDA 8.0 NPP was splitted onto 12 separate libraries.
+ find_cuda_helper_libs(nppc)
+ find_cuda_helper_libs(nppial)
+ find_cuda_helper_libs(nppic)
+ find_cuda_helper_libs(nppicom)
+ find_cuda_helper_libs(nppidei)
+ find_cuda_helper_libs(nppif)
+ find_cuda_helper_libs(nppig)
+ find_cuda_helper_libs(nppim)
+ find_cuda_helper_libs(nppist)
+ find_cuda_helper_libs(nppisu)
+ find_cuda_helper_libs(nppitc)
+ find_cuda_helper_libs(npps)
如果不存在，需要重新安裝CUDA8.0
其他注意事項：
（1）CUDA８.０重新安裝注意一點，一定不要選擇安裝CUDA裏面自帶的驅動，僅安裝第一個選項下的Runtime和Document即可。
（2）CMake的編譯器一定要選擇 VS2013 Win64，即64位編譯器
否則會發生：fatal error LNK1112: 模塊計算機類型“X86”與目標計算機類型“x64”衝突問題
