Qt Creator - pkgconfig problem

Hi everyone,

I have a problem with Qt Creator not seeing include files when using pkgconfig. Everything builds and runs fine, but the text editor does not see the include files and hence does not autocomplete.

My setup is:

Linux 3.6.10-1-ARCH #1 SMP PREEMPT Tue Dec 11 09:40:17 CET 2012 x86_64 GNU/Linux

Qt Creator 2.6.1
Based on Qt 4.8.4 (64 bit)

Example:

gst.pro

QT       += core gui

greaterThan(QT_MAJOR_VERSION, 4): QT += widgets

TARGET = gst
TEMPLATE = app


SOURCES += main.cpp\
        widget.cpp

HEADERS  += widget.h

unix:!macx {
#    INCLUDEPATH += /usr/include/gstreamer-0.10
    CONFIG += link_pkgconfig
    PKGCONFIG += gstreamer-interfaces-0.10
}

main.cpp

#include "widget.h"
#include <QApplication>

int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    Widget w;
    w.show();
    
    return a.exec();
}

widget.h

#ifndef WIDGET_H
#define WIDGET_H

#include <gst/gst.h>
#include <gst/interfaces/xoverlay.h>
#include <QWidget>

class Widget : public QWidget
{
    Q_OBJECT
    
public:
    explicit Widget(QWidget *parent = 0);
    ~Widget();
    
private:
    GstElement *m_pipeline;
    GstElement *m_src;
    GstElement *m_sink;
};

#endif // WIDGET_H

widget.cpp

#include "widget.h"

Widget::Widget(QWidget *parent) :
    QWidget(parent)
{
    gst_init(NULL, NULL);

    m_pipeline = gst_pipeline_new("pipeline");
    m_src = gst_element_factory_make("videotestsrc", "src");
    m_sink = gst_element_factory_make ("xvimagesink", "vSink");

    gst_bin_add_many(GST_BIN(m_pipeline), m_src, m_sink, NULL);
    gst_element_link_many(m_src, m_sink, NULL);

    gst_x_overlay_set_xwindow_id(GST_X_OVERLAY(m_sink), this->winId());

    gst_element_set_state (m_pipeline, GST_STATE_PLAYING);
}

Widget::~Widget()
{
    gst_object_unref(m_pipeline);
}

Sorry for the long post. I don't know if this is a correct place to ask.
I welcome any suggestions.

Thanks,
