New description:

 I checked the code in Portfile, it is stated there that if python version
 is set then variant is created for that version. In my case it is 3.12.
 {{{
 port select --list python
 Available versions for python:
         none
         python312 (active)
 }}}

 and cmake still want to use 3.10 which is wrong. It is even more wrong
 that C build system uses Python as dependency.

Comment:

 What you have selected using `port select` is for your convenience on the
 command line only. Ports will not use it; that would not be
 [wiki:ReproducibleBuilds reproducible].

 The cmake port does not depend on any python.

 cmake depends on curl which depends on libpsl which depends on python310.

 libpsl could potentially be changed to use python312 instead of python310
 but [browser:macports-ports/net/libpsl/Portfile its Portfile] contains
 these cautionary comments:

 {{{#!tcl
 # Please note this port is (indirectly, via cmake) a dependency of the
 # various clang-X ports. When updating the port versions (e.g. python)
 # used here make sure to ensure that the new port being used uses the
 # clang_dependency PortGroup to avoid circular dependencies whilst
 building.
 # See e.g. https://trac.macports.org/ticket/60419

 # DO NOT change this unless you have understood and acted on the above
 comment!
 set py_ver          3.10
 }}}
