I can’t say why the Qt build system does this, but in other cases we know that 'prefix causes problems because the application may end up loading incompatible binaries leading to a crash. That’s especially the case on foreign distros, e.g. when the Guix-installed graphical application loads a plugin from the system’s XDG_* directories. -- Ricardo
