Tnx for your reply

This mean that only run rosrun is sufficient! Also another funny question I have some doubts that I understand cmakelist.txt and launch file completely and their differences! What is the difference between the (cmakelist.txt )and (package.xml) launch file?

Also I did not understand the purpose of .yalm file?

I yaml File is an Configuration File with an special syntax, a Cmakefile is a file for the gcc and it is an instruction how to build a binary from source. The package.xml is an Ros Dependency System where you can specify the Dependency from other Ros Packeges.
