for testing purposes. Do NOT use it to build a distribution Qt package.
It will build and install Qt to ~/.local/lib/Qt and create a tarball
of your Qt build that can be saved and unpacked for testing JS8Call
builds. In the header of this script you can define the version of Qt
you wish to download and build.

This script is restricted to building on Ubuntu 24 Server to ensure your
Qt build is glibc-portable. If you wish to build Qt on a different platform
you must comment out the 'Restrict to Ubuntu 24.04 only' section in the script."
