Compiling QT4 Code using cmake 2.6

Hi Guys!

I have a big Problem. I want to compile my Source Code with Cmake, because later I must add another lib and that isn't possible with qmake.

First here the Code:
widget.h

Code:

#define _WIDGET_H_
 
#include <QApplication>
#include <QFont>
#include <QPushButton>
#include <QWidget>
#include <QtGui>
 
 
class MyWidget : public QWidget{
        Q_OBJECT
public:
	MyWidget(QWidget *parent = 0);
private:
	QLineEdit *lineEdit_v;
	QTableWidget *tablewidget;
	QLineEdit *lineEdit_l;
	QLineEdit *lineEdit_ru;
	int richt[3][200];
	int counter;
	//QLabel *bla;
	//QPushButton *subsampling;
	//QLabel *fertig;
 
public slots:
 
	void copy_list();
};

widget.cpp:

Code:

#include "widget.h"
#include <QtGui>
#include <QHeaderView>
#include <QTableWidget>
 
MyWidget::MyWidget(QWidget *parent)
    : QWidget(parent)
{
 
	//Attribute
	counter=0;
	lineEdit_v = new QLineEdit();
    lineEdit_l = new QLineEdit();
    lineEdit_ru = new QLineEdit();
 
	QPushButton *send = new QPushButton("Ab in die Liste");
 
	tablewidget = new QTableWidget(30, 3, this);
 
	QLabel *label_l = new QLabel(tr("Drehung:"));
	QLabel *label_ru = new QLabel(tr("Dauer:"));
	QLabel *label_v = new QLabel(tr("Speed:"));
 
	//Attributen-Zuweisungen
	lineEdit_v->setMaximumSize( 210, lineEdit_v->maximumSize().height() );
	lineEdit_l->setMaximumSize( 210, lineEdit_l->maximumSize().height() );
	lineEdit_ru->setMaximumSize( 210, lineEdit_ru->maximumSize().height() );
 
	//Anpassung des QTableWidgets
	//
	//Ueberschrift
	QStringList fonts;
	fonts << "Speed" << "Drehung" << "Dauer";
	tablewidget->setHorizontalHeaderLabels(fonts);
 
//SIGNALS AND SLOTS
 
	connect(send, SIGNAL(clicked()),this , SLOT(copy_list()));
 
//LAYOUT
 
 	QVBoxLayout *drehung = new QVBoxLayout();
 	drehung->addWidget(label_l);
 	drehung->addWidget(lineEdit_l);
 
    QVBoxLayout *vor = new QVBoxLayout();
	vor->addWidget(label_v);
    vor->addWidget(lineEdit_v);
 
 	QVBoxLayout *dauer = new QVBoxLayout();
 	dauer->addWidget(label_ru);
 	dauer->addWidget(lineEdit_ru);
 
	QVBoxLayout *linkespalte = new QVBoxLayout();
	linkespalte->addLayout(vor);
	linkespalte ->addLayout(drehung);
	linkespalte->addLayout(dauer);
	linkespalte->addWidget(send);
 
	QVBoxLayout *center = new QVBoxLayout();
	center->addLayout(linkespalte);
	center->addStretch();
 
	QHBoxLayout *end = new QHBoxLayout();
	end->addLayout(center);
	end->addWidget(tablewidget);
 
 
 
 
this->setLayout(end);
 
 
}
 
 
 
void MyWidget::copy_list(){
 
 
	QString speed = lineEdit_v->text();
	QString dreh = lineEdit_l->text();
	QString dauer = lineEdit_ru->text();
 
	QTableWidgetItem *newItem = new QTableWidgetItem(speed);
	QTableWidgetItem *degree = new QTableWidgetItem(dreh);
	QTableWidgetItem *time = new QTableWidgetItem(dauer);
 
	tablewidget->setItem(counter, 0, newItem);
	tablewidget->setItem(counter, 1, degree);
	tablewidget->setItem(counter, 2, time);
 
	counter++;
}

main.cpp

Code:

#include "widget.h"
#include <QtGui>
#include <QHeaderView>
#include <QTableWidget>
 
 
int main(int argc, char *argv[])
{
    	QApplication app(argc, argv);
    	MyWidget widget;
    	widget.show();
    	return app.exec();
}

And at last but not least the CMakeLists.txt

Code:

cmake_minimum_required(VERSION 2.6)
 
 
FIND_PACKAGE(Qt4)
SET(QT_USE_QTXML 1)
INCLUDE(${QT_USE_FILE})
QT4_AUTOMOC(main.cpp widget.cpp widget.h)
ADD_EXECUTABLE(myexe main.cpp widget.cpp)
TARGET_LINK_LIBRARIES(myexe ${QT_LIBRARIES})

I have all the files in a folder. In the console, I am typing:

"cmake-2.6 ."

Code:

okay, all fine until now.
then I must make it:

typing:
"make"

Code:

Where is the problem and why couldn't I compile my program? ("Fehler" means error)

I also testet it with qmake and it works. But I have to do it with cmake.
