I'm rouhgly new to Atom Editor, and I wanted to program my media player, based on vlc/libvlc, with it, but I can't include any files from libvlc. I downloaded it through the terminal with sudo apt-get install libvlc-dev, but now I can't find the files to include it.
Since you installed using apt-get, you should be able to locate the location of all the files from a particular package using apt-file.
$ apt-file list libvlc-dev
If apt-file isn't already on your system, install it.
$ sudo apt-get install apt-file
