# Don't be afraid of this makefile, it is just passing
# arguments to cmake to allow us to keep the wiki pages etc.
# that describe how to build the px4 firmware
# the same even when using cmake instead of make.
#
# Example usage:
#
# make px4_fmu-v2_default 			(builds)
# make px4_fmu-v2_default upload 	(builds and uploads)
# make px4_fmu-v2_default test 		(builds and tests)
#
# This tells cmake to build the nuttx px4_fmu-v2 default config in the
# directory build/px4_fmu-v2_default and then call make
# in that directory with the target upload.

# explicity set default build target
all: px4_sitl_default
