[Ctk-developers] Running error of 'vtkContextDevice2D'

[Quentan Qi]

Hi Julien,

Thank you for your response. I recompiled CTK following your suggestion, but the issue remains. The error is exactly same as before :-(

```
158   if(${VTK_VERSION_MAJOR} GREATER 5)
159   set(VTK_LIBRARIES
160   vtkRenderingContextOpenGL
161   vtkChartsCore
162   ${VTK_LIBRARIES})
```

Any other solutions?

Cheers,
Quentan
