% runtime libraries inside the given mex file.

%
% E.g.,
%
% osxsetoctaverpath('Screen'); would rewrite Screen.mex
% to use the @rpath settings stored in this function.
% We define one rpath as @loader_path, so the runtime dylibs
% are expected in loader_path, e.g., a system library path,
% or the Psychtoolbox folder where the mex files are stored.
% PsychtoolboxPostInstallRoutine copies or symlinks the Octave
% runtime libraries into the mex file folder of PTB, so the mex
% files should always find a dylib for the currently running Octave.

% Add one single rpath: @loader_path. This is the path to our folder where our
% mex file is stored. If we place symlinks to liboctave.dylib and liboctinterp.dylib
% there, then the linker will find them. In absence, the linker will also search the
% users $HOME/lib/ directory as a possible fallback:
lpaths = { '@loader_path' };
% Add all paths in lpaths as potential search paths for the octave
% library directories, ie., as settings for @rpath:
