I’m trying to fix the Macports package of `vtk` that ships 8.2.0 version and that needs the fix for `tp_print` with python 3.8.
The problem is that this version used to build successfully without Python (I did not change the configuration flags provided by the Macports), but now I’m hitting a strange linking error that I’m unable to fix (this is a rerun with `make` not in parallel). It looks like a strange problem with my system, apparently…

I found the problem. As often happens the [Duck Debugging Method](https://en.wikipedia.org/wiki/Rubber_duck_debugging) works amazingly. The issue was that this cmake argument was not removed as expected by Macports.
