Did you install the packages that are reported as missing? Most of them listed in the
compilation instructions as requirements.
If not, this should install their development versions (-dev) that are needed for compilation:
sudo apt install libavformat-dev libavcodec-dev libavutil-dev libswscale-dev openal-dev
You may also need their runtime files to run AM after its compilation. Look up their names without "-dev" on
https://packages.ubuntu.com/ to find their full package names for Ubuntu 19.04 (disco), e.g. "libswscale5". Then exchange their -dev names with those in the above command.
Finally, although your screenshot doesn't show them, you also may need swresample or avresample in their dev and/or runtime versions, since they are also listed in the compilation instructions.
edit: By the way, it would be better if you'd post any errors etc. as text in a code block like I did with my command above. Screenshots take up a lot of space, can only be seen by logged in users, and don't allow quoting or copy & paste if someone wants to address specific parts of them. Just a friendly advice.
