How to define Mex function dependency paths

I have a 'C' mex function (which is of course a dll with .mexa64 extension instead of .dll). It depends on other libraries, so during linking my makefile uses the link time flags -Wl, -rpath,$(INSTALLPATH) to allow the dependencies to be resolved at runtime. Of course I also link with -L$(INSTALLPATH) and -lmylib1 -lmylib2 etc... Both my mex function and its libraries reside in the same folder, and I add that folder to the Matlab 'path' variable in startup.m When I attempt to run my mex program however, Matlab returns with: Invalid MEX-file '$(INSTALLPATH)/mymexfunc.mexa64': libmylib.so.1: cannot open share object file: No such file or directory. Is there something else I need to do so the dependencies can be resolved?

I fixed the whole _SECURE_SCL flag issue. The end result is that for your case, you shouldn't have to make any manual changes but one problem I have is that whenever I run one of the matlab files it works fine the first time, but crashes the second time. Thanks for taking the time to help me out.
