SET(CMAKE_SYSTEM_NAME Linux)
SET(CMAKE_SYSTEM_VERSION 1)

SET(CMAKE_C_COMPILER /Volumes/darwin-arm-v7/bin/arm-cortex_a9-linux-gnueabi-gcc)
SET(CMAKE_CXX_COMPILER /Volumes/darwin-arm-v7/bin/arm-cortex_a9-linux-gnueabi-g++)

SET(CMAKE_FIND_ROOT_PATH /Volumes/darwin-arm-v7/arm-cortex_a9-linux-gnueabi ~/arm-cortex_a9-linux-gnueabi/deps)

SET(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER)
SET(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY)
SET(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)
