Is it possible to define two or more bridges in the same executable?

edit

Hi,

I've been able to compile ros1_bridge from source and to define a bridge for a custom message type. Now, we need to communicate several robots that share several topics. Should I define each bridge independently or can I do it from the same .cpp file?

One more question. Should I recompile all the ros1_bridge file (use the --force-cmake-configure flag) each time I want to add a new bridge?

Thanks!
