Estou tentando escrever um aplicativo OpenCV criando a GUI com o Qt e gerando os makefiles usando o CMake. O problema que tenho é que, quando tento executar omake comando, recebo o erro:

Este arquivo foi gerado usando o moc da 5.2.1. Ele não pode ser usado com os arquivos de inclusão desta versão do Qt. (O moc mudou muito.)

OK. Então eu acho que deveria estar tentando usar o moc do qt4 em vez do qt5 para isso (eu tenho o qt4 e o qt5 instalados). Com certeza eu tenho/usr/bin/moc-qt4 assim como/usr/bin/moc, então eu pensaria que tudo que preciso fazer éinvoke sudo update-alternatives --config moc, mas tudo o que recebo éupdate-alternatives: error: no alternatives for moc. Hummm ...

Então eu acho que o problema está na versão do qt ou no meuCMakeLists.txt, então aqui está o código que eu usei para isso:

cmake_minimum_required(VERSION 2.8.9)
project (Vigil)

    build
    src

    uis

Meus arquivos de origem e cabeçalho estão bastante vazios no momento, mas eu os publicarei também. Quem sabe, talvez o erro esteja aí.

main.cpp:

#include <iostream>
#include "VigilWidget.h"
//#include <QApplication>

int main(int argc, char *argv[]) {
    QApplication app(argc, argv);
    std::cout << "Testing";
    VigilWidget vigil;
    vigil.show();
}

VigilWidget.cpp:

#include "VigilWidget.h"

VigilWidget::VigilWidget(QWidget *parent)
    : QWidget(parent)
{
    ui.setupUi(this);
}

VigilWidget.h:

#ifndef _BGSUBTRACT_H_
#define _BGSUBTRACT_H_

#include "ui_bugView.h"
//#include <QObject>

class VigilWidget : public QWidget{

};
#endif

Enfim, passei a maior parte de dois dias chegando até aqui e realmente aprecio alguma ajuda! Muito obrigado!
