====== CMakeLists.txt ======


Tramite [[neurali:ros catkin]] si può automatizzare la compilazione dei package.

Il file CMakeLists.txt descrive le impostazioni di compilazione, e si può personalizzare.

http://wiki.ros.org/catkin/CMakeLists.txt

Anche in Python! http://docs.ros.org/api/catkin/html/howto/format2/installing_python.html
===== Struttura =====

L'ordine delle voci è importante!
