# [REQUIRED] Add support for the MAVLink communications protocol.
#
# By default MAVLink dialect is hardwired to arudpilotmega. The reason being
# the current codebase supports both PX4 and APM flight stack. PX4 flight stack
# only uses common MAVLink specifications, whereas APM flight stack uses custom
# MAVLink specifications which adds 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.

# In the mean time, it’s possible to define a completely different dialect by defining the
# location and name below.

# check for user defined settings in user_config.pri if not already set as qmake argument
