OpenCV linux how to install FFMPEG

Can someone please help me with a working method on how to install FFMPEG on linux, I have followed several tutorials and they seem to work except after everything FFMPEG is never found in the system, even after several system reboots my last try was from this link Compile FFmpeg on Ubuntu, Debian, or Mint

I did everything in the tutorial but when i run the man ffmpeg it tells me no manual found and OpenCV too does not detect it, I tried calling the Core.getBuildInformation() and the output was:
