I try to compile the code but there comes this error:

build/Debug/GNU-Linux-x86/main.o: In function
`vtkSmartPointer<KeyPressInteractorStyle>::New()':
/usr/local/include/vtk-5.6/vtkSmartPointer.h:113: undefined reference to
`KeyPressInteractorStyle::New();

Are there any changes in the properties (maybe the compiler properties)
which I have to do?
