在Qtcreator的pro文件中添加路径然后重启电脑就可以了

INCLUDEPATH += C:\OpenCV3_3_0\opencv\opencv\build\include\opencv    \

               C:\OpenCV3_3_0\opencv\opencv\build\include\opencv2   \

               C:\OpenCV3_3_0\opencv\opencv\build\include

LIBS +=  -L  C:\OpenCV3_3_0\Qt5_12_3_OpenCV\install\x86\mingw\lib\libopencv_*.a
