[vtkusers] vtkXYPlotActor Problems

[schluperman]

Hi everybody
After solving my last posted errors i got new ones. Can anybody 
interpret this error:

Linking...
plotxy.obj : error LNK2019: unresolved external symbol "public: static 
class vtkXYPlotActor * __cdecl vtkXYPlotActor::New(void)" 
(?New at vtkXYPlotActor@@SAPAV1 at XZ) referenced in function _main
plotxy.obj : error LNK2019: unresolved external symbol "public: void 
__thiscall vtkXYPlotActor::AddInput(class vtkDataSet *,char const 
*,int)" (?AddInput at vtkXYPlotActor@@QAEXPAVvtkDataSet@@PBDH at Z) referenced 
in function "public: void __thiscall vtkXYPlotActor::AddInput(class 
vtkDataSet *)" (?AddInput at vtkXYPlotActor@@QAEXPAVvtkDataSet@@@Z)
Debug/XYPlot.exe : fatal error LNK1120: 2 unresolved externals

Thanks
