You are missing mimick_vendor as a test dependency. I believe that it wouldn't be resolved via the apt packages, as it is only used for testing as specified in the rosidl_typesupport_c package.xml: https://github.com/ros2/rosidl_typesupport/blob/d5d56e65f0efcf0aaf7aa60e63e1acb107c4211a/rosidl_typesupport_c/package.xml#L42

You can resolve this by either fully resolving all of the rosdeps:

rosdep install --from-paths src --ignore-src -y --skip-keys "fastcdr rti-connext-dds-6.0.1 urdfdom_headers"

Or cloning mimick_vendor into your workspace and building it.

Installed mimick_vendor as a binary package. That did it, thanks!
