[Marble-devel] Findings about Marble on Windows

[Torsten Rahn]

Hi Christophe,

Could you add this information to 

http://techbase.kde.org/Projects/Marble/WindowsCompiling

I'd really like Marble one Windows to be a first citizen. 
I think we can only accomplish this if documentation for compiling it becomes 
good. :-)

Best Regards,
Torsten
