[vtkusers] Plotting problem

[Tomás Aguado Gómez]

Dear all:

I am trying to plot a set of Data using vtk with Qt, but when a  
instanciate a vtkXYActor or a vtkXYPlotWidget the linker raises an  
undefined reference, so I guess the libraries are not correctly  
compiled/installed:

1.-¿Do I have to set an special option in cmake when I compile the  
libraries in order to support vtkXY--component--?

2.-¿Does anybody know the name of the shared library where the  
classes above are compiled?

3.-I have the headers of those classes so I don't know why the system  
hasn't compiled them

Thanks in advance!
