-# Android CMake toolchain file, for use with the Android NDK r5-r10d
-# Requires cmake 2.6.3 or newer (2.8.9 or newer is recommended).
-# See home page: https://github.com/taka-no-me/android-cmake
-#
-# Usage Linux:
-# $ export ANDROID_NDK=/absolute/path/to/the/android-ndk
-# $ mkdir build && cd build
-# $ cmake -DCMAKE_TOOLCHAIN_FILE=path/to/the/android.toolchain.cmake ..
-# $ make -j8
-#
-# Usage Windows:
-# You need native port of make to build your project.
-# Android NDK r7 (and newer) already has make.exe on board.
-# For older NDK you have to install it separately.
-# For example, this one: http://gnuwin32.sourceforge.net/packages/make.htm
-#
-# $ SET ANDROID_NDK=C:\absolute\path\to\the\android-ndk
-# $ mkdir build && cd build
-# $ cmake.exe -G"MinGW Makefiles"
-# -DCMAKE_TOOLCHAIN_FILE=path\to\the\android.toolchain.cmake
-# -DCMAKE_MAKE_PROGRAM="%ANDROID_NDK%\prebuilt\windows\bin\make.exe" ..
-# $ cmake.exe --build .
-#
-#
-# Options (can be set as cmake parameters: -D<option_name>=<value>):
-# ANDROID_NDK=/opt/android-ndk - path to the NDK root.
-# Can be set as environment variable. Can be set only at first cmake run.
-#
-# ANDROID_ABI=armeabi-v7a - specifies the target Application Binary
-# Interface (ABI). This option nearly matches to the APP_ABI variable
-# used by ndk-build tool from Android NDK.
-#
-# Possible targets are:
-# "armeabi" - ARMv5TE based CPU with software floating point operations
-# "armeabi-v7a" - ARMv7 based devices with hardware FPU instructions
-# this ABI target is used by default
-# "armeabi-v7a with NEON" - same as armeabi-v7a, but
-# sets NEON as floating-point unit
-# "armeabi-v7a with VFPV3" - same as armeabi-v7a, but
-# sets VFPV3 as floating-point unit (has 32 registers instead of 16)
-# "armeabi-v6 with VFP" - tuned for ARMv6 processors having VFP
-# "x86" - IA-32 instruction set
-# "mips" - MIPS32 instruction set
-#
-# 64-bit ABIs for NDK r10 and newer:
-# "arm64-v8a" - ARMv8 AArch64 instruction set
-# "x86_64" - Intel64 instruction set (r1)
-# "mips64" - MIPS64 instruction set (r6)
-#
-# ANDROID_NATIVE_API_LEVEL=android-8 - level of Android API compile for.
-# Option is read-only when standalone toolchain is used.
-# Note: building for "android-L" requires explicit configuration.
-#
-# ANDROID_TOOLCHAIN_NAME=arm-linux-androideabi-4.9 - the name of compiler
-# toolchain to be used. The list of possible values depends on the NDK
-# version. For NDK r10c the possible values are:
-#
-# * aarch64-linux-android-4.9
-# * aarch64-linux-android-clang3.4
-# * aarch64-linux-android-clang3.5
-# * arm-linux-androideabi-4.6
-# * arm-linux-androideabi-4.8
-# * arm-linux-androideabi-4.9 (default)
-# * arm-linux-androideabi-clang3.4
-# * arm-linux-androideabi-clang3.5
-# * mips64el-linux-android-4.9
-# * mips64el-linux-android-clang3.4
-# * mips64el-linux-android-clang3.5
-# * mipsel-linux-android-4.6
-# * mipsel-linux-android-4.8
-# * mipsel-linux-android-4.9
-# * mipsel-linux-android-clang3.4
-# * mipsel-linux-android-clang3.5
-# * x86-4.6
-# * x86-4.8
-# * x86-4.9
-# * x86-clang3.4
-# * x86-clang3.5
-# * x86_64-4.9
-# * x86_64-clang3.4
-# * x86_64-clang3.5
-#
-# ANDROID_FORCE_ARM_BUILD=OFF - set ON to generate 32-bit ARM instructions
-# instead of Thumb. Is not available for "armeabi-v6 with VFP"
-# (is forced to be ON) ABI.
-#
-# ANDROID_NO_UNDEFINED=ON - set ON to show all undefined symbols as linker
-# errors even if they are not used.
-#
-# ANDROID_SO_UNDEFINED=OFF - set ON to allow undefined symbols in shared
-# libraries. Automatically turned for NDK r5x and r6x due to GLESv2
-# problems.
-#
-# ANDROID_STL=gnustl_static - specify the runtime to use.
-#
-# Possible values are:
-# none -> Do not configure the runtime.
-# system -> Use the default minimal system C++ runtime library.
-# Implies -fno-rtti -fno-exceptions.
-# Is not available for standalone toolchain.
-# system_re -> Use the default minimal system C++ runtime library.
-# Implies -frtti -fexceptions.
-# Is not available for standalone toolchain.
-# gabi++_static -> Use the GAbi++ runtime as a static library.
-# Implies -frtti -fno-exceptions.
-# Available for NDK r7 and newer.
-# Is not available for standalone toolchain.
-# gabi++_shared -> Use the GAbi++ runtime as a shared library.
-# Implies -frtti -fno-exceptions.
-# Available for NDK r7 and newer.
-# Is not available for standalone toolchain.
-# stlport_static -> Use the STLport runtime as a static library.
-# Implies -fno-rtti -fno-exceptions for NDK before r7.
-# Implies -frtti -fno-exceptions for NDK r7 and newer.
-# Is not available for standalone toolchain.
-# stlport_shared -> Use the STLport runtime as a shared library.
-# Implies -fno-rtti -fno-exceptions for NDK before r7.
-# Implies -frtti -fno-exceptions for NDK r7 and newer.
-# Is not available for standalone toolchain.
-# gnustl_static -> Use the GNU STL as a static library.
-# Implies -frtti -fexceptions.
-# gnustl_shared -> Use the GNU STL as a shared library.
-# Implies -frtti -fno-exceptions.
-# Available for NDK r7b and newer.
-# Silently degrades to gnustl_static if not available.
-#
-# ANDROID_STL_FORCE_FEATURES=ON - turn rtti and exceptions support based on
-# chosen runtime. If disabled, then the user is responsible for settings
-# these options.
-#
-# What?:
-# android-cmake toolchain searches for NDK/toolchain in the following order:
-# ANDROID_NDK - cmake parameter
-# ANDROID_NDK - environment variable
-# ANDROID_STANDALONE_TOOLCHAIN - cmake parameter
-# ANDROID_STANDALONE_TOOLCHAIN - environment variable
-# ANDROID_NDK - default locations
-# ANDROID_STANDALONE_TOOLCHAIN - default locations
-#
-# Make sure to do the following in your scripts:
-# SET( CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} ${my_cxx_flags}" )
-# SET( CMAKE_C_FLAGS "${CMAKE_C_FLAGS} ${my_cxx_flags}" )
-# The flags will be prepopulated with critical flags, so don't loose them.
-# Also be aware that toolchain also sets configuration-specific compiler
-# flags and linker flags.
-#
-# ANDROID and BUILD_ANDROID will be set to true, you may test any of these
-# variables to make necessary Android-specific configuration changes.
-#
-# Also ARMEABI or ARMEABI_V7A or X86 or MIPS or ARM64_V8A or X86_64 or MIPS64
-# will be set true, mutually exclusive. NEON option will be set true
-# if VFP is set to NEON.
