@mitsudome-r @xmfcx this change fixes the Debian builds for behavior_path_planner, it'd nice to get it merged before the 2023.07 release.

@xmfcx thanks for the quick review

@xmfcx I've enabled auto-merge for this PR, I don't know why it hasn't merged itself after you approved it. Do you know why?

[xmfcx]

I needed to add myself to global code owners team and re-approve, merge, remove myself from the team.
