[Ipopt] Help with IPOPT linking problems on Windows MSVC

[Jesse Perla]

Sorry for the delay, was out of town.
Thanks for building the binaries, but I won't be able to use them without
separating out the BLAS/LAPACK linking or I will get symbol problems with my
MKL libraries.

I added notes to:
https://projects.coin-or.org/Ipopt/wiki/CompilationHintson windows
compilation.  I am wondering, though, if I should bite the bullet
and use MinGW next time...

Does anyone want me to mail or post up the VS Project files for the building
of sample application and the multilib/debug versions of IPOPT?
