qt - 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:OpenCVuildinclude"

and in my cpp :

#include <opencvcv.h>

The compiler indicates an error:

Cannot open include file: 'opencvcv.h': No such file or directory

but if I write this in my cpp:

#include "C:OpenCVuildincludeopencvcv.h"

it works!

I build the project from within Qt Creator. What am I doing wrong?

Answer 1

You have to run qmake(build->run qmake) to validate changes in the pro file. Qt creator Adding external library (still: Cannot open include file: 'GL/glew.h')
