    * The RQT GUI CPP files use the Qt macros "slots" and "signals".  These conflict
    * with Boost macros of the same name; normally we fix this by adding "-DQT_NO_KEYWORDS"
    * in our CMakeLists file, then using Q_SLOTS and Q_SIGNALS in our source code instead.
    * Since we can't edit the ROS source code, though, we need to define those macros before
    * we include the ROS headers and then undefine them afterwards.
