# Cross-compiling requires CMake 2.6 or newer. Example:
# cmake .. -DCMAKE_TOOLCHAIN_FILE=../XCompile-Android.txt -DHOST=arm-linux-androideabi
# Where 'arm-linux-androideabi' is the host prefix for the cross-compiler. If
# you already have a toolchain file setup, you may use that instead of this
# file. Make sure to set CMAKE_FIND_ROOT_PATH to where the NDK toolchain was
# installed (e.g. "$ENV{HOME}/toolchains/arm-linux-androideabi-r10c-21").
