Hi Robert et al, Just to add/emphasize some points on Rafa's submission:
The general cmake code becomes cleaner, putting all the Android stuff in the toolchain let us to maintain it better. Also we could add different toolchains for different Android versions. Maybe be this approach could be used too for other platforms, like MacOSX or iOS, not having to tweak CMake stuff each time a new OSX/IOS version is released (we could add a new toolchain). Also it would make thinner the current CMake code (that is a already a little monster, you know). Other point is that having the OSG libraries in android as dynamic could reduce quite a lot the size of the final app, which is a good thing. It would be great if somebody could test this submission.
