Gazebo 플러그인 추가

Example of loading a system plugin via the command line:
 
gzserver -s <plugin_filename>
The -s flag indicates it is a system plugin, and <plugin_filename> is the name of a shared library found in GAZEBO_PLUGIN_PATH. For example, to load the RestWebPlugin that ships with Gazebo:
 
gzserver --verbose -s libRestWebPlugin.so
The same mechanism is used by the graphical client, the supported command line flags are the following:
 
Gazebo 7 and earlier: Use -g to load a GUI plugin
Gazebo 8 and later: Use --gui-client-plugin to load a GUI plugin
For example, to load the TimerGUIPlugin:
 
gzclient --gui-client-plugin libTimerGUIPlugin.so
