# Build script for Unix-like systems, using the CMake subsystem
#
# This script covers some common cases. It does *not* install any
# prerequisites though.
#
# For documentation of AVRDUDE's build system, please refer to the
# Wiki:

# https://github.com/avrdudes/avrdude/wiki
# Determine OS type
#
# So far, this script tries to handle three different Unix-like
# systems:
#
# Linux
# FreeBSD
# Darwin (aka. MacOS)
#
# On Linux, if the machine is ARM-based, LINUXSPI and LINUXGPIO are
# enabled.
# On MacOS, an attempt is made to find out whether Mac ports or brew
# are in place, and are assumed to have install the prerequisites.
