# Toolchain config for Android NDK.
# This is expected to be used with a standalone Android toolchain (see

# Usage:
# mkdir build; cd build
# cmake ..; make
# mkdir android; cd android
# cmake -DLLVM_ANDROID_TOOLCHAIN_DIR=/path/to/android/ndk \
# -DCMAKE_TOOLCHAIN_FILE=../../cmake/platforms/Android.cmake ../..
# make <target>
