QCamera error LNK1120 (with Visual Studio+Qt6.5.2)

[Ammie]

I am trying and tryin to define a QCamera Variable in my Code, but always comes an exception or this error:
Qt3BotonCalibrar.obj : error LNK2019: símbolo externo "__declspec(dllimport) public: virtual __cdecl QCamera::~QCamera(void)" (_imp??1QCamera@@UEAA@XZ)
This is happening everytime I write in my MainWIndow.h "QCamera *camarita = new QCamera;"

#pragma once

#include <QtWidgets/QMainWindow>
#include <QPainter>
#include "ui_Qt3BotonCalibrar.h"
#include "ui_WidgetForm_V2.h" //<---V2---- Incluir su librería
#include "ui_WidgetForm_V3.h" //<---V2---- Incluir su librería

#include <QtCore> //Para el timer

#include <iostream> //para los int del tamaño de la pantalla
#include <Windows.h> //para los int del tamaño de la pantalla

#include <QtMultimedia/QCamera>
//#include <QCamera>
//#include <QtMultimediaWidgets/QCameraViewfinder>
#include "qcamera.h"
//#include "QtMultimedia/qcamera.h"
//#include "QtMultimedia/QCameraInfo.h"

class Qt3BotonCalibrar : public QMainWindow
{
Q_OBJECT

public:
Qt3BotonCalibrar(QWidget *parent = Q_NULLPTR);
void paintEvent(QPaintEvent *event);
QTimer reloj;
static int contador;
QCamera camarita = new QCamera;// ("/dev/video0");
//QCameraViewfinder viewfinder = new QCameraViewfinder;
//camarita->setViewfinder(viewfinder);

It seems to be a problem with libreria or includes, but I have already tried to add <QCamera>, and also added "$(QTDIR)\include;$(QTDIR)\include\QtMultimedia;" in Proyect-Properties in Visual Studio, but no way...
I have checked and the Files are in those folders, but still not working and I am running out of ideas.
Could you please help me?

QCamera

You need to add
QT += multimedia
to your .pro file.
