remove the system dependencies of ROS package?

edit

After installing a ros package, when I did rosdep check <package_name> , it has displayed some missing system dependencies that were not taken care of, during apt-get install . So, I installed them using rosdep install. However when I want to remove the ros package ,

sudo apt-get purge ros-*

sudo apt-get purge python-ros*

sudo apt-get autoremove

running the above three commands seem to be removing only the ros dependencies and not the system dependencies. How do I remove the system dependencies as well in this case? Thank you.

PS: I am trying to install only a single ros package on Ubuntu 16.04 ARM.
