[osg-users] [build] osgslice build failure on OSX

[Voerman, L.]

Hi Robert,
The reference comes from include/osgViewer/GraphicsWindow near the end of
the file:
USE_GRAPICSWINDOW_IMPLEMENTATION(Carbon)

I've created a pull request with a possible fix here
<https://github.com/openscenegraph/OpenSceneGraph/pull/837>; however
- I dont have an apple so I can't test anything
- I got unsure if it's possible to build with mutiple windowing systems,
and whether we should prefer cocoa if available.

On the other hand my PR will fix the build on modern apple systems without
making the build impossible on carbon systems. I don't know if the carbon
system is used anyway; the current master tree will probably not link the
osgSlice example when building with the carbon windowing system.
Laurens.
