+FindCups
+--------
+
+Find the CUPS printing system.
+
+Set CUPS_REQUIRE_IPP_DELETE_ATTRIBUTE to TRUE if you need a version which
+features this function (i.e. at least 1.1.19)
+
+Imported targets
+^^^^^^^^^^^^^^^^
+
+This module defines :prop_tgt:`IMPORTED` target ``Cups::Cups``, if Cups has
+been found.
+
+Result variables
+^^^^^^^^^^^^^^^^
+
+This module will set the following variables in your project:
+
+``CUPS_FOUND``
+ true if CUPS headers and libraries were found
+``CUPS_INCLUDE_DIRS``
+ the directory containing the Cups headers
+``CUPS_LIBRARIES``
+ the libraries to link against to use CUPS.
+``CUPS_VERSION_STRING``
+ the version of CUPS found (since CMake 2.8.8)
+
+Cache variables
+^^^^^^^^^^^^^^^
+
+The following cache variables may also be set:
+
+``CUPS_INCLUDE_DIR``
+ the directory containing the Cups headers
+#]=======================================================================]
