FindCups
--------
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)
