I looked at this and it only works for linux.  Although it may be highly
unlikely, given that wxpython and wxwidgets can be build against gtk on
windows and msys2 provides gtk2, gtk3, and as of a few days ago gtk4
packages, there is always the possibility that this could happen on
windows.  Since msys2 builds use wx-config, this shouldn't be a
difficult change.

You should always respect the devs preference even though it may be
incorrect.  A simple check to see if wxWidgets_CONFIG_OPTIONS has
already been defined should suffice.  If you are really feeling
motivated, a warning to the uninformed developer would be useful.
