I know of at least one project (libopenjpeg) where the use 
of two build systems has the effect that nobody knowns where 
the headers should be installed.
Apart from that, I doubt that it will be easy to port the 
build system. And finally, iiuc, your FFmpeg build works 
fine, it seems your VS project fails to build, or am I wrong?

(which errors?)

Sorry, I personally do not find it constructive to ask for a 
second build system. The one we use is regularly tested on 
very different build systems (and was optimized heavily for 
FFmpeg's needs).
I of course understand you don't share my opinion though.

Please do not top-post here, Carl Eugen
