# ------------------------------------------------------------------------------
# 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-hard with NEON" - ARMv7 based devices with hardware FPU instructions and hardfp
# "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.

# 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 ARMEABI_V7A_HARD 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.
