To know how many ROS feature packages are in a project, the fastest way is to search package.xml directly in the project, and search for CMakeLists.txt is also possible. One risk of package.xml is that it may be the package.xml of the workspace, not the package.xml of the feature package. CMakeLists.txt should be the feature package, and the second line should have the name of the feature package.
Of course, what if it might be a normal C++ project? Of course, the above method should also be a good method, at least better than nothing.
It is clear at a glance which feature packs Prometheus has like XTDrone GAAS.
px4_command is really a feature package
