I have written one simple xfce4 plugin, it works very well on my Debian computer.
On Debia 8, the .so and .desktop file are located at /usr/lib/xfce4/panel-plugins and /usr/share/xfce4/panel-plugins directories respectively.
However, When I tested it on Fedora 24, .so and .desktop files are placed in /usr/lib64/xfce4/panel/plugins/ and /usr/share/xfce4/panel/plugins/.
So, for portable reason, how do I find the right location to place these two files in different Linux distribution.
