+# Android CMake toolchain file, for use with the Android NDK r5-r8
+# Requires cmake 2.6.3 or newer (2.8.5 or newer is recommended).
+# See home page: https://github.com/taka-no-me/android-cmake
+#
+# The file is mantained by the OpenCV project. The latest version can be get at
+# http://code.opencv.org/projects/opencv/repository/revisions/master/changes/android/android.toolchain.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 Linux (using standalone toolchain):
+# $ export ANDROID_STANDALONE_TOOLCHAIN=/absolute/path/to/android-toolchain
+# $ 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 (or 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_STANDALONE_TOOLCHAIN=/opt/android-toolchain - path to the
+# standalone toolchain. This option is not used if full NDK is found
+# (ignored if ANDROID_NDK is set).
+# 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" - matches to the NDK ABI with the same name.
+# See ${ANDROID_NDK}/docs/CPU-ARCH-ABIS.html for the documentation.
+# "armeabi-v7a" - matches to the NDK ABI with the same name.
+# See ${ANDROID_NDK}/docs/CPU-ARCH-ABIS.html for the documentation.
+# "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" - matches to the NDK ABI with the same name.
+# See ${ANDROID_NDK}/docs/CPU-ARCH-ABIS.html for the documentation.
+# "mips" - matches to the NDK ABI with the same name
+# (It is not tested on real devices by the authos of this toolchain)
+# See ${ANDROID_NDK}/docs/CPU-ARCH-ABIS.html for the documentation.
+#
+# ANDROID_NATIVE_API_LEVEL=android-8 - level of Android API compile for.
+# Option is read-only when standalone toolchain is used.
+#
+# ANDROID_TOOLCHAIN_NAME=arm-linux-androideabi-4.6 - the name of compiler
+# toolchain to be used. The list of possible values depends on the NDK
+# version. For NDK r8c the possible values are:
+#
+# * arm-linux-androideabi-4.4.3
+# * arm-linux-androideabi-4.6
+# * arm-linux-androideabi-clang3.1
+# * mipsel-linux-android-4.4.3
+# * mipsel-linux-android-4.6
+# * mipsel-linux-android-clang3.1
+# * x86-4.4.3
+# * x86-4.6
+# * x86-clang3.1
+#
+# ANDROID_FORCE_ARM_BUILD=OFF - set ON to generate 32-bit ARM instructions
+# instead of Thumb. Is not available for "x86" (inapplicable) and
+# "armeabi-v6 with VFP" (is forced to be ON) ABIs.
+#
+# ANDROID_NO_UNDEFINED=ON - set ON to show all undefined symbols as linker
+# errors even if they are not used.
+#
+# ANDROID_SO_UNDEFINED=OFF - set ON to allow undefined symbols in shared
+# libraries. Automatically turned for NDK r5x and r6x due to GLESv2
+# problems.
+#
+# LIBRARY_OUTPUT_PATH_ROOT=${CMAKE_SOURCE_DIR} - where to output binary
+# files. See additional details below.
+#
+# ANDROID_SET_OBSOLETE_VARIABLES=ON - if set, then toolchain defines some
+# obsolete variables which were used by previous versions of this file for
+# backward compatibility.
+#
+# 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 will be set true, mutually
+# exclusive. NEON option will be set true if VFP is set to NEON.
+#
+# LIBRARY_OUTPUT_PATH_ROOT should be set in cache to determine where Android
+# libraries will be installed.
+# Default is ${CMAKE_SOURCE_DIR}, and the android libs will always be
+# under the ${LIBRARY_OUTPUT_PATH_ROOT}/libs/${ANDROID_NDK_ABI_NAME}
+# (depending on the target ABI). This is convenient for Android packaging.
