 > ok, next week I will try to look in to the nsis script to see if is it
 possible to add this option during the installation process.

 some steps may be:

 - add e new installer gui-section "Customize python" (or something like
 that)

 - add some explanations to the gui-section "Customize python": e.g.
 compatible wxpython, numpy, matplotlib, etc. are needed, ...

 - default option: %GRASS_PYTHON% is the packaged python

 - user option: ask the user for the %PATH% to the user wanted python


 technical implementation - some pointers:

 - let point %GRASS_PYTHON% to the user defined python:

 a few years ago I've added two string replace functions to the nsis-
 script:

 https://trac.osgeo.org/grass/browser/grass/trunk/mswindows/GRASS-
 Installer.nsi.tmpl#L104

 https://trac.osgeo.org/grass/browser/grass/trunk/mswindows/GRASS-
 Installer.nsi.tmpl#L338

 use some of these functions to adjust %GRASS_PYTHON% and %PYTHONHOME% in
 ''env.bat'' to the user defined paths by a e.g. if/else statement
