function compile_msndfile(varargin)
% COMPILE_MSNDFILE Compile msndfile.
%
% COMPILE_MSNDFILE will compile the msndfile suite of Mex extensions and copy
% the resulting binaries into the package directory '+msndfile'.
%
% Input parameters
% ----------------
%
% COMPILE_MSNDFILE has the following options (passed as parameter/value pairs):
%
%   Name        | Type    | Description                                  | Default
%   ==================================================================================
%   Debug       | logical | whether to build msndfile with debug symbols | false
%   Destdir     | char    | where to install the package directory       | '.'
%   PkgDir      | char    | the name of the package directory            | '+msndfile'
