How do I make Qt5 to see QMultimedia

[davidlamhauge]

I have upgraded QtCreator to 2.7.1, on my Ubuntu 13.10.
Suddenly QMultimedia can't be seen by QtCreator.
The multimedialibraries are at /usr/include/Qt5/ so I have tried the following in the .pro file.
It doesn't work.

INCLUDEPATH += /usr/include/Qt5/
QT += multimedia
CONFIG += multimedia

INCLUDEPATH += /usr/include/Qt5/
QT += multimedia
CONFIG += multimedia

To copy to clipboard, switch view to plain text mode 

When I try to

#include <Qt5/QMultimedia/QAudioFormat>

#include <Qt5/QMultimedia/QAudioFormat>

To copy to clipboard, switch view to plain text mode 

I get an error, because in "qaudioformat.h" it includes <QtMultimedia>?!? QtMultimedia is deprecated, or...?
It is odd and beyond me...

Can anyone advise me to solve this problem?

Make sure you are using qmake from the proper Qt version (Qt5 and not Qt4).
