# - Try to find the Cups printing system
# Once done this will define
#
#  CUPS_FOUND - system has Cups
#  CUPS_INCLUDE_DIR - the Cups include directory
#  CUPS_LIBRARIES - Libraries needed to use Cups
#  CUPS_VERSION_STRING - version of Cups found (since CMake 2.8.8)
#  Set CUPS_REQUIRE_IPP_DELETE_ATTRIBUTE to TRUE if you need a version which
#  features this function (i.e. at least 1.1.19)
