This change adds several of the pieces needed to build Ceres on Android. The port is incomplete, since GFlags doesn't build which causes the tests to not build. However, simple_bundle_adjuster builds and runs on the phone. Thanks to Scott Ettinger for the original version of the minimal GLog implementation which made this port possible. The Ceres logs go to the various Android logging levels, as documented in miniglog/glog/logging.h. To control the Android build, this adds a new CMake build option: -DBUILD_ANDROID=ON/OFF However, users may not want to set this manually, and should instead run the script found in android/build_android.sh. The script calls the NDK to make a standalone toolchain, downloads the android-cmake toolchain, then configures CMake to cross-compile Ceres to Android. Note: At time of writing, the android-cmake toolchain that the script downloads from Google Code doesn't work with the latest Jellybean NDK. It's possible to manually hack the toolchain file to make it build by setting the compiler version and manually setting the path to the STL includes. I don't yet have a patch suitable for upstreaming to http://android-cmake.googlecode.com. Change-Id: Icb615be203145e87413d6acd05883171a395499d
