# 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 px4fmu-v2_default 			(builds)
# make px4fmu-v2_default upload 	(builds and uploads)
# make px4fmu-v2_default test 		(builds and tests)
#
# This tells cmake to build the nuttx px4fmu-v2 default config in the
# directory build_nuttx_px4fmu-v2_default and then call make
# in that directory with the target upload.

#  explicity set default build target
all: posix_sitl_default

# Parsing
# --------------------------------------------------------------------
# assume 1st argument passed is the main target, the
# rest are arguments to pass to the makefile generated
# by cmake in the subdirectory
