Updated 2020-11-28: thanks, Ennio! Should now build after new Raspberry Pi OS and Vice changes

This was freely adapted from the build docs, Linux-Native-Howto.txt, which has more info if you get stuck.
If you’re feeling fancy and want nice GUI controls and sound recording and menu stuff, try
./configure --disable-pdf-docs --enable-lame --with-mpg123 --enable-shared-ffmpeg --enable-x64 --enable-native-gtk3ui --enable-desktop-files
This will give you desktop icons too. I’m not sure in the apt line is quite right, though â€” but I’ve had my doubts about all those CIL entries, ‘cos I think they pull in Mono/.Net, and who would want to use that?
