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. -# -# Change Log: -# - initial version December 2010 -# - April 2011 -# [+] added possibility to build with NDK (without standalone toolchain) -# [+] support cross-compilation on Windows (native, no cygwin support) -# [+] added compiler option to force "char" type to be signed -# [+] added toolchain option to compile to 32-bit ARM instructions -# [+] added toolchain option to disable SWIG search -# [+] added platform "armeabi-v7a with VFPV3" -# [~] ARM_TARGETS renamed to ARM_TARGET -# [+] EXECUTABLE_OUTPUT_PATH is set by toolchain (required on Windows) -# [~] Fixed bug with ANDROID_API_LEVEL variable -# [~] turn off SWIG search if it is not found first time -# -
