[pcampolucci]

follow up from #2639

Submodule of ppzlink updated to latest version

[pcampolucci]

@gautierhattenberger this is the final one. Hope I did not forget anything

[gautierhattenberger]

almost, pprzlink ref is good, but the key_generator submodule have been rewind to your backup branch version

[pcampolucci]

ok done

@gautierhattenberger it fails again. It builds on my machine. I am out of ideas D:

I missed the modified ABI message, it has one extra parameter, so now it is failing with other modules using it:

 grep -r MsgOPTICAL_FLOW *
modules/computer_vision/opticflow_module.c:    AbiSendMsgOPTICAL_FLOW(FLOW_OPTICFLOW_ID, now_ts,
modules/sensors/opticflow_pmw3901.c:  AbiSendMsgOPTICAL_FLOW(FLOW_OPTICFLOW_PMW3901_ID,
modules/ctrl/optical_flow_landing.c:  AbiBindMsgOPTICAL_FLOW(OFL_OPTICAL_FLOW_ID, &optical_flow_ev, vertical_ctrl_optical_flow_cb);
modules/ctrl/optical_flow_hover.c:  AbiBindMsgOPTICAL_FLOW(OFH_OPTICAL_FLOW_ID, &optical_flow_ev, ofh_optical_flow_cb);
modules/stereocam/stereocam.c:    AbiSendMsgOPTICAL_FLOW(STEREOCAM2STATE_SENDER_ID, now_ts,

Oh these are new from the updated master, I will just remove the distance_quality parameter then. Its not that important

[pcampolucci]

@gautierhattenberger It works!

[gautierhattenberger]

good job
