Didn’t know about this file, thank you.
It seems this is not an issue anymore but here is why started this topic:
I bundle julia programming language along with SlicerCAT and I wasn’t able to build a package (pyjulia) because its dependency (PyCall) used to be built against python.exe while pyjulia determined that it is invoked from PythonSlicer.exe (pyjulia used to raise an exception about this).
But as I figured out later the problem was within Slicer build tree python library is copied to Slicer-build and the inconsistency was invoked by that: PyCall links to python-install/bin/python39.dll and pyjulia links to Slicer-build/bin/python39.dll.
This is not an issue when SlicerCAT is installed (tested).
