Can MATLAB use prototype files to load shared C library if that library has dependencies?

I'm trying to use MATLAB's loadlibrary function to load a shared library that has dependencies on a Linux RHEL8 workstation using a prototype file.
>> loadlibrary(library_path,@libfuncprototype)
Error using loadlibrary
There was an error loading the libary
"/opt/Lib64/libfunc.so"
libsubfunc.so.5: cannot open shared object file: No such file or directory
Caused by:
Error using loaddefinedlibrary
libsubfunc.so.5: cannot open shared object file: No such file or directory
Both libfunc.so and libsubfunc.so.5 (not their real names but sufficient for explaining the issue) exist in /opt/Lib64. When I run:
system(ldd('/opt/Lib64/libfunc.so')
the return shows that dependent library libsubfunc.so.5 was found
I investigated setting LIB_LIBRARY_PATH and LIB_RUN_PATH prior to the loadlibrary command, but I still get the same result when running loadlibary.
Questions:
- Can MATLAB load shared libraries using prototype file if the libraries have dependencies?
- How do I tell MATLAB to search in the same directory as the library for dependencies?
