I am using rosserial, and rosserial_arduino with custom messages.
Within the ros project I only use rosserial_arduino to build a helloworld arduino sketch (the chatter example), and include custom message types.
I then grab ros_lib and take it over to a platformio project, because the arduino ide installed by apt is very old (~1.0), and I need to use a more powerful board than an AVR anyway.
Currently I am using a ATSAMD51 Feather M4 Express board, and have successfully connected it to rosserial and published/subscribed to topics.
Anyway, that works - I can even upload the example to an arduino micro, all within the ros project.
This is quite neat, one command to build the ros workspace including the arduino sketch,
one further command to upload, but the 32u4 just ran out of memory (I think I can strip some unused stuff from ros_lib?).
The issue is that the first build always fails with the following error ros_lib does not exist, and then the second build succeeds.
I am using catkin build.

Any help appreciated. The tutorials I found seem to be light and out of date and I am no CMake expert.
