Result Variables
^^^^^^^^^^^^^^^^

This will define the following variables:

``lilv_FOUND``
  True if the system has the lilv library.
``lilv_INCLUDE_DIRS``
  Include directories needed to use lilv.
``lilv_LIBRARIES``
  Libraries needed to link to lilv.
``lilv_DEFINITIONS``
  Compile definitions needed to use lilv.

Cache Variables
^^^^^^^^^^^^^^^

The following cache variables may also be set:

``lilv_INCLUDE_DIR``
