`ros2 launch ov_msckf...`: ERROR: flag 'logtostderr' was defined more than once

[diplodocuslongus]

OpenVINS was built successfully with ROS2 humble, ubuntu 22.04, ceres 2.0.

But when I run:

ros2 launch ov_msckf subscribe.launch.py config:=euroc_mav

I get the error:

flag 'logtostderr' was defined more than once (in files './src/logging.cc' and $HOME/builds/glog/src/logging.cc')

Obviously this is related to the fact that I have built my own glog locally, but why would ros2 launch ... pick up this local logging.cc file? Also there is no logging.cc in ./src (there is only one location where in my $HOME I can find a logging.cc, it is in $HOME/builds/glog/src/logging.cc.

The full error message is:

$ source install/setup.bash
$ ros2 launch ov_msckf subscribe.launch.py config:=euroc_mav

I still don't know how this is happening, but uninstalling my locally built glog solved the issue. I leave this issue open as this may be due to how the openVINS build with colcon is setup (it shouldn't fetch more than one location for glog).
