Hello everyone!

I want to build a custom Slicer3D using your template by Kitware. I followed steps thoroughly but, at the end of the building phase, i get an error envolving some kind of VTK feature called vtkTeemPython.

i don’t know from where this error comes and Visual Studio’s traceback is not helping to be honest…

The error code is MSB8066 and its something like that:

Could anyone help me finding out what is happening?  
Thanks in advance

First of all, I’d try running the superbuild again, without deleting anything. Sometimes there are hiccups that simply resuming the build fixes.

If you see the same error, then please share the whole log, because then it is possible that there are other issues that cause this one.

Here’s the full log of my last build:

Alright. I posted my suggestion on the ticket. The first issue seems to be an easy one.
