the same way as you install any other package on your distribution?
and the same for all other missing dev-packages

apt-get install libass-dev

https://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu clearly lists 
"libass-dev" as well as states the install command

Get the Dependencies

Copy and paste the whole code box for each step. First install the 

sudo apt-get update
sudo apt-get -y install autoconf automake build-essential libass-dev 
libfreetype6-dev \
   libsdl2-dev libtheora-dev libtool libva-dev libvdpau-dev 
libvorbis-dev libxcb1-dev libxcb-shm0-dev \
   libxcb-xfixes0-dev pkg-config texinfo zlib1g-dev
