-# Ceres build script for Android. To build the ceres.so libraray for Android,
-# cd into an empty directory and run the script. Usage:
-#
-#   build_android.sh \
-#   <path to Android NDK> \
-#   <path to Eigen> \
-#   <path to Ceres source>
-#
-#   make
-#
-# This script exists only to make it easier to get Ceres building on Android;
-# as one can see from the code below, it is only a matter of extracting a
-# standalone NDK toolchain from the NDK, and getting the right arguments to
-# CMake to get it to work.
-#
-# Android NDK version r5 or higher is required. Jellybean does not work out of
-# the box, since the android-cmake toolchain is not yet updated to for it.
-#
-# Note: You may wish to run 'ccmake .', the CMake curses GUI, in order to tweak
-# the build parameters that are set by default. There are a few settings to
-# consider changing:
-#
-# SCHUR_SPECIALIZATIONS:
-#
-# Consider if enabling the schur specializations is a big enough win for the
-# problem you are solving, since compiling the schur specializations
-# considerably increases the binary size. Disable them by running 'ccmake .',
-# finding the SCHUR_SPECIALIZATIONS variable, hitting enter (toggling to "off"),
-# pressing 'c' to generate, then 'g' to generate and exit, followed by 'make'.
-#
-# EXECUTABLE_OUTPUT_PATH
-# LIBRARY_OUTPUT_PATH
-# LIBRARY_OUTPUT_PATH_ROOT:
-#
-# In normal CMake builds, where you do an out of source build, the source
-# directory is untouched when building. However, by default the Android CMake
-# toolchain selects locations under your *source* tree for the final library
-# and binary destinations. For example, if your Ceres git tree is under
-# ceres-solver.git/ and the build directory you are using is
-# ceres-android-bin/, the resulting binaries will live in ceres-solver.git/
-# (but not the intermediate .o files!) By changing the variables
-# EXECUTABLE_OUTPUT_PATH, LIBRARY_OUTPUT_PATH, and LIBRARY_OUTPUT_PATH_ROOT to
-# something under e.g. ceres-android-bin/ then true out-of-ource builds work.
