From Ulrich Hertlein, "Attached; here's a summary of the changes:

- CMakeLists.txt
-- don't look for GL when compiling for iOS (device or simulator), look for OGLES instead
-- use architecture i386 for simulator
-- removed iphoneos-version-min for simulator

- examples/osgviewerIPhone/CMakeLists.txt
-- added build dependencies for osgdb_osg, osgdb_freetype, osgdb_imageio
-- added framework QuartzCore link dependency

- src/osgDB/CMakeLists.txt
-- don't link against Carbon on iOS (device or simulator)

- src/osgPlugins/freetype/CMakeLists.txt
-- don't link against OpenGL on iOS device or simulator

- src/osgViewer/CMakeLists.txt
-- link against OpenGLES on iOS (device or simulator)

- src/osgPlugins/imageio/CMakeLists.txt
-- compile ReaderWriterImageIO_IOS.cpp as Objective-C++
