ninja: error: '/usr/lib/libSDL2-2.0.so.0.3000.10', needed by 'bin/plasma/kcms/systemse
ttings/kcm_gamecontroller.so', missing and no known rule to make it

The most recent version on my system was sdl2 2.30.11-1

Finding 2.30.10 in package archives https://archive.archlinux.org/packages/s/sdl2/, then installing it with sudo pacman -U “package_name”
