This script is intended to replicate the funcionalities of the Makefile recipe versionNumber.auto.o
It overwrites the file versionNumber.auto.f90 in the source code tree, compilation is done by meson

Probably it is worth deactivating it for the version distributed with pyPI and fixing the .f90 file instead
