Mixing compiled matlab shared libraries with mex code.

I have some matlab code that invokes mex code (compiled with VS2013). I have both Debug and Release builds of the mex code, and can adjust my system (windows) PATH prior to starting up Matlab so that when I invoke that mex function from Matlab, it invokes the desired build configuration.
Now, I want to bundle up the matlab code into a DLL with the matlab compiler. If I don't add the mex DLLs as additional files required in the .PRJ GUI, the compiled matlab code can't find it at runtime. But if I do add the mex code, the resulting compiled matlab library is "build configuration dependent" -- i.e. if I added the debug build of the mex code, the library won't work from a release build of an executable program client of the compiled matlab library, and vice versa. So, what I want to do is to get a compiled matlab library that doesn't know about the mex code, but which can find it at runtime using the normal PATH-related load procedure, since the desired mex DLL will be in the same folder (Debug or Release) as the executable program client of the compiled matlab library. But I don't seem to be able to find a way to accomplish this goal. Any thoughts?

The best way to do this is to place the MEX file in a relative path to "ctfroot":
Normally, in Windows, "ctfroot" is %temp%\username\mcrCachexx.

What about the A.mexw64.auth file that is not generated if you don't include the mex file in the mcc build. How do you get around that?
