[vtkusers] cmake error: no qvtkwidget.h is found

[Yifei Li]

Hi all,

I just made some progress.  But I got a new problem - a linking error:

CMakeFiles/editor.dir/editorwindow.o: In function 
`Ui_MainWindow::setupUi(QMainWindow*)':
editorwindow.cpp:(.text._ZN13Ui_MainWindow7setupUiEP11QMainWindow[Ui_MainWindow::setupUi(QMainWindow*)]+0x492): 
undefined reference to `QVTKWidget::QVTKWidget(QWidget*, 
QFlags<Qt::WindowType>)'
 
I fixed the previous problem by changing the name of the include header 
'qvtkwidget.h' (included in ui_editor.h)  to 'QVTKWidget.h"

However, the 'ui_editor.h' is automatically genereated after typing 
'make'.  So is this a bug of cmake??   On the same machine where I 
successfully built SimpleView,  I did not have this problem.

My computer is running Fedora 9 and cmake version is 2.4.

Any ideas?
