The build system should ask which compiler to use. You can set it either
via envars (like CC), switches to the build system, or by editing the
build system files (like Makefile). If it's Cmake, there's a 'ccmake'
something something (read the manual for it). You could install, for
example, /opt/gcc-15/bin and then tell it /opt/gcc-15/bin/gcc for the
compiler.

You might also try temporarily hiding your system compiler, but that's
kind of hacky.

You sure this won't work? https://github.com/darktable-org/darktable/releases/download/release-5.6.0/Darktable-5.6.0-x86_64.AppImage
