With Makefile build, generate_component_general.py was called twice during
build, which did not happen with the ninja build.
This created a race condition with the following error in rare cases:
Traceback (most recent call last):
File "/__w/PX4-Autopilot/PX4-Autopilot/src/lib/component_information/generate_component_general.py", line 79, in <module>
save_compressed(filename)
File "/__w/PX4-Autopilot/PX4-Autopilot/src/lib/component_information/generate_component_general.py", line 33, in save_compressed
with open(filename, 'r') as content_file:
FileNotFoundError: [Errno 2] No such file or directory: '/__w/PX4-Autopilot/PX4-Autopilot/build/px4_sitl_default/component_general.json'
make[3]: *** [src/lib/component_information/CMakeFiles/component_information_header.dir/build.make:68: component_general.json] Error 1
Merging the targets avoids the duplicate execution.
The following exception occurs in some rare cases (but only with make build: NO_NINJA_BUILD=1 px4_sitl_default):
Traceback (most recent call last):

This also simplifies the API a bit, since we anyway have to change the
drivers to pass additional information (the bus device index).
The orientation flag is merged with the rotation.
Only needed for Makefile-based builds:
gmake[3]: *** No rule to make target 'src/modules/flight_mode_manager/FlightTasks_generated.hpp', needed by 'events/px4.json'. Stop.
- sending protocol
- uorb event message & template methods for argument packing
- libevents submodule to send common events and handle json files
- cmake maintains a list of all (PX4) source files for the current build
(PX4 modules + libs), which is used to extract event metadata and
generate a json file
