Comment (by easye):

 RE:   python3

 It doesn't seem that python3 is needed to actually build wabt but is used
 in various tests.

 After deactivating all my installed Python ports, my configuration run
 picked up the system Python:

 {{{
 -- Found Python3: /usr/bin/python3 (found suitable version "3.9.6",
 minimum required is "3.5") found components: Interpreter
 }}}

 1.  Can I just let this default to the system Python?

 2.  Otherwise, is there a way to specify a minimum Python version rather
 than depending on an exact version?
