Qt添加opencv庫

下載編譯好的opencv庫（這裏以32位爲例）：[https://github.com/huihut/OpenCV-MinGW-Build/tree/OpenCV-3.3.1]

下載完成後在.pro文件中添加下列代碼：

win32 {
INCLUDEPATH += H:\OpenCV-MinGW-Build-OpenCV-3.3.1\include\
INCLUDEPATH += H:\OpenCV-MinGW-Build-OpenCV-3.3.1\include\opencv
INCLUDEPATH += H:\OpenCV-MinGW-Build-OpenCV-3.3.1\include\opencv2
LIBS += H:\OpenCV-MinGW-Build-OpenCV-3.3.1\bin\libopencv_*.dll
}

添加完成後，將.dll文件複製一份到編譯出的.exe文件夾中
