tracetools

Building

If tracing is not enabled when building, or if LTTng is not found, then this package will not do anything.

To enable tracing:

Install LTTng:

$ sudo apt-get install lttng-tools lttng-modules-dkms liblttng-ust-dev

Build with the WITH_LTTNG flag:

$ colcon build --cmake-args " -DWITH_LTTNG=ON"

Check if tracing is enabled (after sourcing):
```
$ ros2 run tracetools tracetools_status
```

By default, the steps above will not lead to trace data being generated, and thus they will have no impact on execution.

LTTng has to be enabled: TODO mention scripts
