[ros-users] [Discourse.ros.org] [Next Generation ROS] Adding clang thread safety analysis for ROS2 core packages

[Thomas Moulard via Discourse.ros.org]

We have two ways IMHO:

1. Keep TSA optional and write a colcon mixin to enable this behavior.
2. Inject the statements you quoted everywhere using the `*-extras.cmake` mechanism.

My feeling is that, keeping this opt-in per-package will be challenging because mixing the clang and GNU standard libraries is probably unsafe. So it would need to be a global on/off flag. 2. is most likely too brutal of a change so 1. could be the best option.
