FindChromaprint
---------------

Finds the Chromaprint library.

Imported Targets
^^^^^^^^^^^^^^^^

This module provides the following imported targets, if found:

``Chromaprint::Chromaprint``
  The Chromaprint library

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

This will define the following variables:

``Chromaprint_FOUND``
  True if the system has the Chromaprint library.
``Chromaprint_INCLUDE_DIRS``
  Include directories needed to use Chromaprint.
``Chromaprint_LIBRARIES``
  Libraries needed to link to Chromaprint.
``Chromaprint_DEFINITIONS``
  Compile definitions needed to use Chromaprint.

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

The following cache variables may also be set:

``Chromaprint_INCLUDE_DIR``
  The directory containing ``chromaprint.h``.
``Chromaprint_LIBRARY``
  The path to the Chromaprint library.
