This was a fairly recent update that went unnoticed because it uses a cached variable.
When I previously updated Android cmake I didn't noticed this.
Basically the issue was that Android cmake was no longer setting ${LIBRARY_OUTPUT_PATH_ROOT}
and instead only setting it to ${CMAKE_SOURCE_DIR} if it was passed a variable.
Same PR is open on the android cmake repo here https://github.com/taka-no-me/android-cmake/pull/37

# 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
|

|
|
# 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.
