# Configure libudev environment
#
# UDEV_FOUND - system has a libudev
# UDEV_INCLUDE_DIR - where to find header files
# UDEV_LIBRARIES - the libraries to link against udev
# UDEV_STABLE - it's true when is the version greater or equals to 143 - version when the libudev was stabilized in its API
# An "udev" target is created when found
