If it's just one .so and that library is compatible with basic libs
such as glibc and has no further big dependencies, then there may be
a simpler way than cx_freeze or even snap/docker/etc.

Python 2 will likely be available for quite some more years as an
optional package. But even with a self-compiled version, you should
be able to put the required libraries somewhere and set
LD_LIBRARY_PATH or maybe LD_PRELOAD accordingly. For a few depending
libs, this works well, but it gets really nasty if glibc or big
frameworks such as GTK are involved.
