This approach unifies much of the code handling the clean up of OpenGL graphics data, avoids lots of local mutexes and static variables that were previously required,
and enables the clean up scheme to be easily extended by users providing their own GraphicsObjectManager subclasses.

My changes:
-------------------
- I changed the cmake files and added a toolchain for building OSG in Android. The toolchain is based on the one used at OpenCV. For building OSG for android you just need to do:
mkdir build_android_static_gles2 && cd build_android_static_gles2
cmake .. -DANDROID_NDK=<path-to-the-android-ndk>
-DCMAKE_TOOLCHAIN_FILE=../PlatformSpecifics/Android/android.toolchain.cmake
-DOPENGL_PROFILE="GLES2"
-DDYNAMIC_OPENTHREADS=OFF
-DDYNAMIC_OPENSCENEGRAPH=OFF
-DANDROID_NATIVE_API_LEVEL=15 # optional
-DANDROID_ABI=armeabim #optional
-DCMAKE_INSTALL_PREFIX=<path-to-the-install-path> #optional
make -j 8
make install
The OPENGL_PROFILE works as expected, changing it to "GLES1" it builds and links OSG using GLES1.
The DYNAMIC_OPENTHREADS/DYNAMIC_OPENSCENEGRAPH parameters also allows to build the dynamic libraries
- I also added some build fixes for android related to the texture formats and added some missing USE_OSG_SERIALIZER_WRAPPER in the osg serializer library to support loading osgb files in static."

see http://www.openscenegraph.org/projects/osg/browser/OpenSceneGraph/trunk/src/CMakeLists.txt
the option OSG_MSVC_GENERATE_PLUGINS_AND_WRAPPERS_MANIFESTS is set to ON only after the subdirectories are added,
this causes /MANIFEST:NO while the option is ON after the first configure, generate.
if this option is moved (i.e. above the ADD_SUBDIRECTORY statement) results are as expected.
attached you will find the correct CMakeLists.txt

"- In order to build against GLES1 we execute:
$ mkdir build_android_gles1
$ cd build_android_gles1
$ cmake .. -DOSG_BUILD_PLATFORM_ANDROID=ON -DDYNAMIC_OPENTHREADS=OFF
-DDYNAMIC_OPENSCENEGRAPH=OFF -DANDROID_NDK=<path_to_android_ndk>/
-DOSG_GLES1_AVAILABLE=ON -DOSG_GL1_AVAILABLE=OFF
-DOSG_GL2_AVAILABLE=OFF -DOSG_GL_DISPLAYLISTS_AVAILABLE=OFF -DJ=2
-DOSG_CPP_EXCEPTIONS_AVAILABLE=OFF
$ make
If all is correct you will have and static OSG inside:
build_android_gles1/bin/ndk/local/armeabi.
- GLES2 is not tested/proved, but I think it could be possible build
it with the correct cmake flags.
- The flag -DJ=2 is used to pass to the ndk-build the number of
processors to speed up the building.
- make install is not yet supported."
From Robert Osfield, refactor of Wang Rui's original osg2 into 3 parts - parts placed into osgDB, the ReaderWriter placed into src/osg/Plugin/osg and wrappers into src/osgWrappers/serializers/osg
Also, there was also a small bug in osgDB's CMakeLists.txt that was causing an error when I tested with CMake 2.4.4.
IF(${OSG_DEFAULT_IMAGE_PLUGIN_FOR_OSX} STREQUAL "quicktime")
was changed to
IF(OSG_DEFAULT_IMAGE_PLUGIN_FOR_OSX STREQUAL "quicktime")
"
Notes from Robert Osfield, I've merged osgWidget trunk, and added/changed CMakeLists.txt file to make it suitable for inclusion in the core OSG, and moved imagery/scripts/shaders out into OpenSceneGraph-Data
