0c7ba8e03e don't install udev rules by default, as it may pollute the system 
For cmake call with -DINSTALL_UDEV_RULES=ON for the rules to be
installed during the default install/uninstall stages.

For autotools call "make install-udev-rules" or "make uninstall-udev-

The rules file will be installed to "/etc/udev/rules.d".
