[Ipopt] Using a Third Party Software in IPOPT MA57 Interface

[Tony Kelman]

Are you sure you were running make test before, or were you just building 
the Matlab interface? To run standalone executables like from make test then 
you'll need to add -lcsparse to other link flags too, not just in the 
MatlabInterface folder. I think there are some ADDLIBS configure variables 
you can set for this.

Unfortunately It is still not working.
