INCLUDEPATH in qmake project file doesn't work

Question

I\'ve got a problem with include in a qmake project. In my .pro file I\'ve got:

INCLUDEPATH += \"C:\\OpenCV\\build\\include\"

and in my cpp

Answer 1

I have the same question, before building or running, you should qmake(Build=>qmake) it.

My configurations for INCLUDEPATH:

INCLUDEPATH+=D:\opencv\opencv\build\include
INCLUDEPATH+=D:\opencv\opencv\build\include\opencv
INCLUDEPATH+=D:\opencv\opencv\build\include\opencv2
