RQT : .moc file not found

Hello, I'm trying to compile a gui application that interfaces with ROS. This application has in turn to deal with QML itself and therefore has to use QT MOC system. I'm sure it's a silly mistake but as I've a deadline coming soon, I can't afford spending too much time on it.

And here is my class definition that requires the MOC system :

class ColorZones : public QObject
{
    Q_OBJECT
    Q_PROPERTY(QColor zone READ getZoneColor WRITE setZoneColor NOTIFY zoneColorChanged) 

public:
    explicit ColorZones(QObject *parent = nullptr);

    QColor getZoneColor(const int zone) const {return _zonesColor[zone];};
    void setZoneColor(const int,const Proximity);

signals:
    void zoneColorChanged();

private:
    boost::array<QColor,6> _zonesColor;

};

And the QML snippet :

Canvas {
        id:canvas
            anchors.fill: parent
        onPaint:{
            var ctx = canvas.getContext('2d');
            ctx.lineWidth = 2
            ctx.strokeStyle = "black"

            //ZONE 0
            ctx.fillStyle = ColorZones.getZoneColor(0)

            ctx.beginPath()
            ctx.moveTo(310,301)
            ctx.arcTo(10,1,600,600,65,50)
            ctx.closeSubpath()

            ctx.beginPath()
            ctx.moveTo(310,181);
            ctx.lineTo(310,301);
            ctx.closeSubpath();

            ctx.fill()
            ctx.stroke()
          }
}

Connections {
               target: onZoneColorChanged
               onColorChanged: canvas.requestPaint()
       }

For now, I got this error message :

fatal error: guiMain.moc: No such file or directory compilation terminated. gui/CMakeFiles/gui.dir/build.make:98: recipe for target 'gui/CMakeFiles/gui.dir/src/guiMain.cpp.o' failed make[2]: * [gui/CMakeFiles/gui.dir/src/guiMain.cpp.o] Error 1 CMakeFiles/Makefile2:2110:

However, when I inspect the build gui directory, the guiMain.moc is present. What am I suppose to do ? Thanks.
