# [REQUIRED] Add support for the MAVLink communications protocol.
# Mavlink dialect is hardwired to arudpilotmega for now. The reason being
# the current codebase supports both PX4 and APM flight stack. PX4 flight stack
# only usese common mavlink specifications, wherease APM flight stack uses custom
# mavlink specifications which add to common. So by using the adupilotmega dialect
# QGC can support both in the same codebase.
#
# Once the mavlink helper routines include support for multiple dialects within
# a single compiled codebase this hardwiring of dialect can go away. But until then
# this "workaround" is needed.
