Hi all!
Friday on late I’ve resolved and I promised to myself to reply here today.
But I see only today that David has answer with the same solution that I’ve discovered too.
So thanks for the support and for answering. Probably that isn’t a best practice but for now is the only way that permits me to obtain an external library based on vtk wheel.
In any case if you got a better way to do that i’ll appreciate to know it.
For now thanks to all
