Unable to run a deployed file in linux: error while loading shared libraries: libmwlaunchermain.so

I have created a deployable XYZ but unable to launch it even after configuring LD_LIBRARY_PATH. I keep getting the error

error while loading shared libraries: libmwlaunchermain.so: cannot open shared object file: No such file or directory

I'm able to launch it with the accompanying run_XYZ.sh script which temporarily sets the environment. I tried everything I know and this isn't something I'm doing for the first time. I have created and successfully deployed applications on linux systems but can't recall which version of Ubuntu I used then. I'm currently trying this on Ubuntu 16.04.

$ echo $LD_LIBRARY_PATH

/usr/local/MATLAB/MATLAB_Runtime/v84/runtime/glnxa64:/usr/local/MATLAB/MATLAB_Runtime/v84/bin/glnxa64:/usr/local/MATLAB/MATLAB_Runtime/v84/sys/os/glnxa64:/usr/local/MATLAB/MATLAB_Runtime/v84/sys/opengl/lib/glnxa64

The file it's complaining about is very much there in the second directory on the path above. However, when I try ldconfig -p, the list doesn't show libmwlaunchermain.so

Any ideas what I'm missing here?

Thanks.
