MCR cache fails to copy over external dependencies for compiled binary

Hello,

I've compiled my Matlab script using mcc.

mcc('-m', '-c', '-R', '-singleCompThread', '-R' , '-nodisplay' , '-R' , '-nojvm', 'my_script.m', '-d', 'build-binary', '-a', '/path/to/external/libs');

but when I try running it, I get the following error

------------------------------------------
Setting up environment variables

LD_LIBRARY_PATH is .:/usr/local/matlab/MATLAB_Runtime/v99//runtime/glnxa64:/usr/local/matlab/MATLAB_Runtime/v99//bin/glnxa64:/usr/local/matlab/MATLAB_Runtime/v99//sys/os/glnxa64:/usr/local/matlab/MATLAB_Runtime/v99//sys/opengl/lib/glnxa64
Error using loadlibrary
/root/.mcrCache9.9/my_c0/my_script/libMyLib_thunk_glnxa64.so: cannot open shared object file: No such file or directory

The file that it claims to be missing is in the same directory as the compiled binary of my MATLAB script, but MATLAB fails to copy it over to the .mcrCache.

How can I tell it to do that?

My current "workaround" is to run the program once so that the cache is generated, manually copy over the missing library, and rerun it. But this is a slow hack, and I need the correct solution.

Operating system

Debian GNU/Linux 9 (stretch)

Software

MATLAB Runtime v99 for Linux (not the full MATLAB installation)

Thanks!
