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.
