# ------------------------------------------------------------------------------
# Android CMake toolchain file, for use with the CrystaX NDK
# Requires cmake 3.0 or newer (3.2 or newer is recommended).
#
# Usage Linux:
# $ mkdir build && cd build
# $ cmake -DCMAKE_TOOLCHAIN_FILE=$NDK/cmake/toolchain.cmake ..
# $ make -j8
#
# Usage Windows:
# $ mkdir build && cd build
# $ cmake.exe -G"MinGW Makefiles"
# -DCMAKE_TOOLCHAIN_FILE=%NDK%\cmake\toolchain.cmake
# -DCMAKE_MAKE_PROGRAM="C:\absolute\path\to\the\crystax-ndk\prebuilt\windows\bin\make.exe" ..
# $ cmake.exe --build .
#
#
# Options (can be set as cmake parameters: -D<option_name>=<value>):
# 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+neon" - same as armeabi-v7a, but
# sets NEON as floating-point unit
# "armeabi-v7a+vfpv3" - same as armeabi-v7a, but
# sets VFPV3 as floating-point unit (has 32 registers instead of 16)
# "armeabi-v7a-hard" same as armeabi-v7a, but using -mhard-float
# "armeabi-v6+vfp" - tuned for ARMv6 processors having VFP
# "x86" - IA-32 instruction set
# "mips" - MIPS32 instruction set
#
# 64-bit ABIs
# "arm64-v8a" - ARMv8 AArch64 instruction set
# "x86_64" - Intel64 instruction set (r1)
# "mips64" - MIPS64 instruction set (r6)
#
# ANDROID_NATIVE_API_LEVEL=android-9 - level of Android API compile for.
# Option is read-only when standalone toolchain is used.
#
# ANDROID_TOOLCHAIN_VERSION=gcc-5 - the version of the toolchain to be
# used. The list of possible values depends on the NDK version.
# For CrystaX NDK 10.3.1 the possible values are:
#
# * gcc-4.9
# * gcc-5
# * clang-3.6
# * clang-3.7
#
# ANDROID_TOOLCHAIN_NAME=arm-linux-androideabi-4.9 - the name of compiler
# toolchain to be used. This is combination of ANDROID_ABI and ANDROID_TOOLCHAIN_VERSION
# values. Use it only if you really need it. Usually, it's enough to specify
# ANDROID_ABI and ANDROID_TOOLCHAIN_VERSION - ANDROID_TOOLCHAIN_NAME is deduced from them.
# The list of possible values depends on the NDK version. For CrystaX NDK 10.3.1
# the possible values are:
#
# * aarch64-linux-android-4.9
# * aarch64-linux-android-5
# * aarch64-linux-android-clang3.6
# * aarch64-linux-android-clang3.7
# * arm-linux-androideabi-4.9
# * arm-linux-androideabi-5
# * arm-linux-androideabi-clang3.6
# * arm-linux-androideabi-clang3.7
# * mips64el-linux-android-4.9
# * mips64el-linux-android-5
# * mips64el-linux-android-clang3.6
# * mips64el-linux-android-clang3.7
# * mipsel-linux-android-4.9
# * mipsel-linux-android-5
# * mipsel-linux-android-clang3.6
# * mipsel-linux-android-clang3.7
# * x86-4.9
# * x86-5
# * x86-clang3.6
# * x86-clang3.7
# * x86_64-4.9
# * x86_64-5
# * x86_64-clang3.6
# * x86_64-clang3.7
#
# ANDROID_FORCE_ARM_BUILD=OFF - set ON to generate 32-bit ARM instructions
# instead of Thumb. Is not available for "armeabi-v6+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_shared - 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.
# 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 -fexceptions.
#
# 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_STANDALONE_TOOLCHAIN - cmake parameter
# ANDROID_STANDALONE_TOOLCHAIN - environment variable
# 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.
#
