How can I integrate a shared C++ library that I built using the Library Compiler into Excel?

Hi,

I have built a C++ shared library using the Matlab Library Compiler and I want to figure out how to incorporate this into Excel WITHOUT creating an Excel Add-in by using the Library Compiler. I can integrate most C++ functions that I have built into Excel as functions and I want to do the same with the C++ shared library but the usual methods of doing so aren't working for me. Essentially I have to write a script in VBA that links to the appropriate DLL and then imports the C++ functions as functions that can be used in Excel.
