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
Qt Code: 
  1. #define _WIDGET_H_
  2.  
  3. #include <QApplication>
  4. #include <QFont>
  5. #include <QPushButton>
  6. #include <QWidget>
  7. #include <QtGui>
  8.  
  9.  
  10. class MyWidget : public QWidget{
  11.         Q_OBJECT
  12. public:
  13. 	MyWidget(QWidget *parent = 0);
  14. private:
  15. 	QLineEdit *lineEdit_v;
  16. 	QTableWidget *tablewidget;
  17. 	QLineEdit *lineEdit_l;
  18. 	QLineEdit *lineEdit_ru;
  19. 	int richt[3][200];
  20. 	int counter;
  21. 	//QLabel *bla;
  22. 	//QPushButton *subsampling;
  23. 	//QLabel *fertig;
  24.  
  25. public slots:
  26.  
  27. 	void copy_list();
  28. };

widget.cpp:
Qt Code: 
  1. #include "widget.h"
  2. #include <QtGui>
  3. #include <QHeaderView>
  4. #include <QTableWidget>
  5.  
  6. MyWidget::MyWidget(QWidget *parent)
  7.     : QWidget(parent)
  8. {
  9.  
  10. 	//Attribute
  11. 	counter=0;
  12. 	lineEdit_v = new QLineEdit();
  13.     lineEdit_l = new QLineEdit();
  14.     lineEdit_ru = new QLineEdit();
  15.  
  16. 	QPushButton *send = new QPushButton("Ab in die Liste");
  17.  
  18. 	tablewidget = new QTableWidget(30, 3, this);
  19.  
  20. 	QLabel *label_l = new QLabel(tr("Drehung:"));
  21. 	QLabel *label_ru = new QLabel(tr("Dauer:"));
  22. 	QLabel *label_v = new QLabel(tr("Speed:"));
  23.  
  24. 	//Attributen-Zuweisungen
  25. 	lineEdit_v->setMaximumSize( 210, lineEdit_v->maximumSize().height() );
  26. 	lineEdit_l->setMaximumSize( 210, lineEdit_l->maximumSize().height() );
  27. 	lineEdit_ru->setMaximumSize( 210, lineEdit_ru->maximumSize().height() );
  28.  
  29. 	//Anpassung des QTableWidgets
  30. 	//
  31. 	//Ueberschrift
  32. 	QStringList fonts;
  33. 	fonts << "Speed" << "Drehung" << "Dauer";
  34. 	tablewidget->setHorizontalHeaderLabels(fonts);
  35.  
  36. //SIGNALS AND SLOTS
  37.  
  38. 	connect(send, SIGNAL(clicked()),this , SLOT(copy_list()));
  39.  
  40. //LAYOUT
  41.  
  42.  	QVBoxLayout *drehung = new QVBoxLayout();
  43.  	drehung->addWidget(label_l);
  44.  	drehung->addWidget(lineEdit_l);
  45.  
  46.     QVBoxLayout *vor = new QVBoxLayout();
  47. 	vor->addWidget(label_v);
  48.     vor->addWidget(lineEdit_v);
  49.  
  50.  	QVBoxLayout *dauer = new QVBoxLayout();
  51.  	dauer->addWidget(label_ru);
  52.  	dauer->addWidget(lineEdit_ru);
  53.  
  54. 	QVBoxLayout *linkespalte = new QVBoxLayout();
  55. 	linkespalte->addLayout(vor);
  56. 	linkespalte ->addLayout(drehung);
  57. 	linkespalte->addLayout(dauer);
  58. 	linkespalte->addWidget(send);
  59.  
  60. 	QVBoxLayout *center = new QVBoxLayout();
  61. 	center->addLayout(linkespalte);
  62. 	center->addStretch();
  63.  
  64. 	QHBoxLayout *end = new QHBoxLayout();
  65. 	end->addLayout(center);
  66. 	end->addWidget(tablewidget);
  67.  
  68.  
  69.  
  70.  
  71. this->setLayout(end);
  72.  
  73.  
  74. }
  75.  
  76.  
  77.  
  78. void MyWidget::copy_list(){
  79.  
  80.  
  81. 	QString speed = lineEdit_v->text();
  82. 	QString dreh = lineEdit_l->text();
  83. 	QString dauer = lineEdit_ru->text();
  84.  
  85. 	QTableWidgetItem *newItem = new QTableWidgetItem(speed);
  86. 	QTableWidgetItem *degree = new QTableWidgetItem(dreh);
  87. 	QTableWidgetItem *time = new QTableWidgetItem(dauer);
  88.  
  89. 	tablewidget->setItem(counter, 0, newItem);
  90. 	tablewidget->setItem(counter, 1, degree);
  91. 	tablewidget->setItem(counter, 2, time);
  92.  
  93. 	counter++;
  94. }

main.cpp

  7. int main(int argc, char *argv[])
  8. {

  11.     	widget.show();
  12.     	return app.exec();
  13. }

And at last but not least the CMakeLists.txt

Qt Code: 
  1. cmake_minimum_required(VERSION 2.6)
  2.  
  3.  
  4. FIND_PACKAGE(Qt4)
  5. SET(QT_USE_QTXML 1)
  6. INCLUDE(${QT_USE_FILE})
  7. QT4_AUTOMOC(main.cpp widget.cpp widget.h)
  8. ADD_EXECUTABLE(myexe main.cpp widget.cpp)
  9. TARGET_LINK_LIBRARIES(myexe ${QT_LIBRARIES})

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

"cmake-2.6 ."

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

typing:
"make"

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.
