qt + opengl gluLookAt issue

i'm writing simple 2d game and i have to do some stuff in qt. Game runs good , it was written in vs 2015 , now i moved it into qt creator.

There is opengl widget to display graphic. I've added things in .pro file and i can use opengl function except gluLookAt(used in timer function cscenaqt) , i get error :

    cscenaqt.obj:-1: błąd: LNK2019: unresolved external symbol gluLookAt referenced in function "protected: virtual void __cdecl cScenaQt::timerEvent(class QTimerEvent *)" (?timerEvent@cScenaQt@@MEAAXPEAVQTimerEvent@@@Z)

Here is opengl widget file

#ifndef CSCENAQT_H
#define CSCENAQT_H

#include <QWidget>
#include <QGLWidget>

class cScenaQt : public QGLWidget
{
    Q_OBJECT        // must include this if you use Qt signals/slots

public:
    cScenaQt(QWidget *parent);

protected:

    void initializeGL();

    void resizeGL(int w, int h);

    void paintGL();
    void mouseMoveEvent(QMouseEvent * event);
    void keyPressEvent(QKeyEvent* e);

    void timerEvent(QTimerEvent *event);
private:
    float m_x,m_y;
    int m_timer_id;
};

#endif // CSCENAQT_H

Here is .pro file

How can i fix this issue and is there some way to allow user to use more than one key in qt(i know it was possible in opengl with glkeyupfun and keydown , smth like this)?
