The ros tutorials that I follow say that the package.xml file has to contain two types of dependencies xml tag which are "build_depend" and "exec_depend". However, when I opened package.xml file of my package, I saw three different dependency xml tag. These are "build_depend", "exec_depend", and "build_export_depend".
What is "build_export_depend" tag used for ?
Two days ago, I built my package by using the command "catkin_make".
Did this build operation add that tag into xml file ?
