FindFLAC++
--------

Finds the FLAC++ library.

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

This module provides the following imported targets, if found:

``FLAC++::FLAC++``
  The FLAC++ library

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

This will define the following variables:

``FLAC++_FOUND``
  True if the system has the FLAC++ library.
``FLAC++_INCLUDE_DIRS``
  Include directories needed to use FLAC++.
``FLAC++_LIBRARIES``
  Libraries needed to link to FLAC++.
``FLAC++_DEFINITIONS``
  Compile definitions needed to use FLAC++.

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

The following cache variables may also be set:

``FLAC++_INCLUDE_DIR``
  The directory containing ``FLAC++/all.h``.
``FLAC++_LIBRARY``
  The path to the FLAC++ library.
