but was not able to use them for a while. Attached are changes to
OsgAndroidMacroUtils.cmake that allow the deps to be found by cmake.
Specifically, all FIND_PATH commands require the
NO_CMAKE_FIND_ROOT_PATH option to actually find paths. This is odd
because if you inspect CMAKE_FIND_ROOT_PATH it appears to be empty. I
would expect it to have no effect at all.
I also needed to remove quotes from this line in order for headers to be found:
set(FREETYPE_INCLUDE_DIRS "${FREETYPE_DIR}/include
${FREETYPE_DIR}/include/freetype/config")
Assuming this script worked in the past, it seems like cmake behavior
may have changed at some point. I'm using cmake version 2.8.12.2."

2nd - Script to use a 3rd party directory with basic libraries: libjpeg,libpng,libtiff,giflib,freetype,curl,gdal.
3rd - Change in the GLES library loading for Android. That should make GLES2 work properly.
4rth- Included two defines RGB8_OES and RGBA8_OES as a substitute in GLES for RGB8 and RGBA8
5th - OpenGL and GLSL version identification changed to recognize GLES versions properly
"
"- 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."
