# This script is expected to run inside a docker container which has the Raspberry Pi toolchain
# and required prerequisites:
#   - pkg-config
#   - libusb-1.0-0-dev
#   - libudev-dev
#
# /build corresponds to the current directory when the docker container is run and it is expected
# that the following directory structure has been setup:
#
#   - /build/Open-ZWave/open-zwave  - git repository containing the desired version of OpenZWave
#   - /build/gateway                - git repository containing the gateway software
