Thanks!

CMake is now an official requirement for mingw-cross-env.

This is a bug in the openscenegraph package and should be fixed,
either via a patch (which should also be presented to upstream),
or via some $(SED) actions.

Nevertheless, the additional -L... option wouldn't harm. If
upstream refuses that addition, consider adding it conditionally,
i.e. only when openscenegraph was built for static linking.

If you need any help with that, please let me know.

Thanks. Except for the overly long compile command, it looks great!
