FindCups
--------
Find the Common UNIX Printing System (CUPS).
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
^^^^^^^^^^^^^^^^
.. versionadded:: 3.15
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
