Add dependencies to rosidl in CMakeLists.txt (#349)

braineniac · web-flow · commit 2fba9997808f · 2021-09-27T07:37:09.000+02:00
I followed this tutorial and without adding dependencies to rosidl, the error message: ImportError: /home/dan/work/microros_ws/install/hw_msgs/lib/libhw_msgs__rosidl_generator_c.so: undefined symbol: std_msgs__msg__Header__fini pops up(in my case because of std_msgs) when publishing with the agent. I had no other errors in the compilation process. In the official tutorial it's also present: https://docs.ros.org/en/foxy/Tutorials/Single-Package-Define-And-Use-Interface.html
