Hi, couple of doubts:
when we use
source devel/setup.bash, is it safe to say that we are restarting that particular shell with the updated values environmental or export values?
for message file creation,in the Cmake file, what is the difference between find_package(), message_generation() and catkin_package(). Based on my understanding from reading the comments in the Cmake file, they are all pretty much the same and makes that package available to that function. so why didn’t who ever created this system, replace them with just one of the above-mentioned functions instead of three.
