commit f8688e6dfc8efd7dd1033844039efee983263b42
Author: Marcus Müller <address@hidden>

    Modified add_custom_command to not try to execute ""
    
    former custom command called ""; this works fine on build systems were
    this is expanded by shell, but fails on some of my systems where
    add_custom_command's COMMAND parameter is directly executed (because
    there's no executable "").
