It also needs to handle an existing binary. Just how is it supposed to handle it?

Right now with meson it is either a full path, or just the name in case it was missing at build time (I have not checked if the launcher actually consults $PATH).

Anyway, what would be the desired approach to tell libvirt the runtime path?

I was thinking about something like:
  option('runtime_path_exe', type: 'string', value: 'exe', description: 'runtime path of exe')
  runtime_path_exe = get_option('runtime_path_exe')
  if not get_option('runtime_path_exe').enabled()
    runtime_path_exe = find_program(runtime_path_exe, required: true).path()
  conf.set_quoted('EXE', runtime_path_exe)
