FindSndFile
-------
Finds the SndFile library.
Imported Targets
^^^^^^^^^^^^^^^^
This module provides the following imported targets, if found:
``SndFile::sndfile``
The SndFile library
Result Variables
^^^^^^^^^^^^^^^^
This will define the following variables:
``SndFile_FOUND``
True if the system has the SndFile library.
``SndFile_VERSION``
The version of the SndFile library which was found.
``SndFile_WITH_EXTERNAL_LIBS``
True if the library was built with Xiph codecs.
For compatibility with upstream, the following variables are also set:
``SndFile_WITH_MPEG``
``SndFile_VERSION_MAJOR``
``SndFile_VERSION_MINOR``
``SndFile_VERSION_PATCH``
``SndFile_LIBRARY``
``SndFile_LIBRARIES``
``SNDFILE_LIBRARY``
``SNDFILE_LIBRARIES``
``SNDFILE_INCLUDE_DIR``
