Building @rules_ros//examples/bazel_simple_example:publisher fails

[ahans]

After setting up a local workspace as described in README.md, building a "real" example that depends on ROS packages fails:

We are still missing some parts of the middleware. Coming soon.

+1 subscribed. I have seemed to run into a different issue:

fatal error: rosgraph_msgs/msg/detail/clock__rmw_cyclonedds_cpp.h: No such file or directory
   10 | #include "rosgraph_msgs/msg/detail/clock__rmw_cyclonedds_cpp.h"
      |          ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
compilation terminated.

I have created a repo to help those interested in trying to reproduce. https://github.com/willcbaker/ros2_bazel The project uses a osrf/ros:humble-deskptop container with bazel v5.3.2 and the WORKSPACE file as instructed in https://github.com/ApexAI/rules_ros#workspace-setup
