Missing UDev dependency in tutorial

[netrick]

In the "Compiling SFML with CMake" tutorial: http://www.sfml-dev.org/tutorials/2.3/compile-with-cmake.php there is a missing dependecy for Linux.

UDev is not listed and on Ubuntu 15.04 it's not installed by default. The actual package name is "libudev-dev".

Without UDev, CMake gives following errors:

(click to show/hide)

-- UDev not found.
-- UDev: You can specify includes: -DUDEV_PATH_INCLUDES=/opt/udev/include
--       currently found includes: UDEV_INCLUDE_DIR-NOTFOUND
-- UDev: You can specify libs: -DUDEV_PATH_LIB=/opt/udev/lib
--       currently found libs: UDEV_LIBRARIES-NOTFOUND
CMake Error at cmake/Modules/FindUDev.cmake:49 (MESSAGE):
  Could not find UDev library
Call Stack (most recent call first):
  src/SFML/Window/CMakeLists.txt:215 (find_package)


-- Configuring incomplete, errors occurred!

Looks like that got accidentally removed when creating the new dependency list for SFML 2.3, because it was listed in 2.2.

Thanks for the report, will fix this soon.
