[Ipopt] Building Ipopt under Visual Studio

[Stefan Vigerske]

Hi,

What are the unresolved references?

TAUCS is an alternative to MUMPS, HSL, PARDISO,...
Thus, the IpTAUCSSolverInterface.cpp should only be compiled if you also
have the TAUCS linear solver that works with Ipopt.

Difficult to say without knowing more details.
