You need both a JPEG library as well as the RPI development libraries available. It seems bullseye has newer versions. I don't have a Bullseye available at the moment, but I think libjpeg9-dev might work as the JPEG library dev package. Not sure if the VideoCore (VC) development library is still available on bullseye. At least if you run with dtoverlay=vc4-kms-v3d in /boot/config.txt, this method of taking screenshots won't work anyway, even if you get it to compile.

What do you intend to use the tool for? Taking screenshot of your desktop? If so, using something shutter might work better.

Screenshot tool is best for making screenshots over ssh for all cases, x, console, or within ES for my themes or gaming shots

As I don't have any Bullseye installation at the moment, I cannot easily fix this right now. Pull requests welcome.
