I'm running Qt5.0.0 msvc2010 and I'm trying to add 3 files to a very basic project using the "add existing files" option of Qt Creator. The only intent of this project is to display a window created with Qt Designer.
The 3 files are mainwindow.h, mainwindow.cpp and mainwindow.ui automatically generated by Qt Designer.
When I try to compile, I get this: fatal error C1083: Cannot open include file: 'mainwindow.h': No such file or directory.

The files are correctly located in my projet file and qmake runs fine.
Qt Code: 
  1. QT += widgets
  2. SOURCES += \
  3.     main.cpp \
  4.     ../test/mainwindow_test_form/mainwindow.cpp[ATTACH=CONFIG]8718[/ATTACH]
  5.  
  6. FORMS += \
  7.     ../test/mainwindow_test_form/mainwindow.ui
  8.  
  9. HEADERS += \
  10.     ../test/mainwindow_test_form/mainwindow.h
To copy to clipboard, switch view to plain text mode 
My main.cpp files look like this:
Qt Code: 
  1. #include <QApplication>
  2. #include <QtGui>
  3. #include "mainwindow.h"
  4. int main(int argc, char *argv[])
  5. {
  6.     QApplication app(argc, argv);
  7.     MainWindow theMainWindow;
  8.     theMainWindow.show();
  9.     return app.exec();
  10. }
To copy to clipboard, switch view to plain text mode 

I tried to put the 3 files in different locations (in or out of the project) and I still get the same result.
Any Suggestions?

Thanks!


I have attached a screenshot of my project in Qt Creator too. It might help.
