One of teams in here try to write a crosscompling script , which would target the Win platform , although he doesn't know to provide the self - build binary of CEGUI for Win platform :
http://forum.freegamedev.net/viewtopic.php?f=41&t=4279
then cross-compiling CEGUI under Linux would be a great help Preferably by making a script that can do it.
So if it happen to someone to have such script in the dark corners of his hard disc ( or other data medium ) please pastebin it here .
EDIT: I just reposted it here, From the >>Development<< subforum .
