[vtkusers] X11 CMake Errors on Mac

[Berkowitz, Benjamin M]

Hi David,

I uninstalled and reinstalled both Qt and VTK.  I tried building the EventQtSlotConnect example, and I'm getting this error:

Linking CXX executable EventQtSlotConnect.app/Contents/MacOS/EventQtSlotConnect
Undefined symbols for architecture x86_64:
  "QVTKWidget::QVTKWidget(QWidget*, QFlags<Qt::WindowType>)", referenced from:
      Ui_EventQtSlotConnect::setupUi(QMainWindow*) in EventQtSlotConnect.cxx.o
  "vtkEventQtSlotConnect::New()", referenced from:
      vtkSmartPointer<vtkEventQtSlotConnect>::New() in EventQtSlotConnect.cxx.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make[2]: *** [EventQtSlotConnect.app/Contents/MacOS/EventQtSlotConnect] Error 1
make[1]: *** [CMakeFiles/EventQtSlotConnect.dir/all] Error 2
make: *** [all] Error 2


Do you have any ideas?

Thanks,
Ben
