[Ipopt] Building IPOPT on MAC using Intel MKL

[Andreas Waechter]

Hi Simeon,

Sorry for the late reply.

I'm glad you got things to work in the end, I just wanted to follow up 
with a comment:

In principle, Ipopt compilation should work if you have ifort instead of 
gfortran (as long as your Fortran compiler is consistent with your C and 
C++ compilers).  If you want to see the error message that the configure 
script complains about, you need to look into the correct config.log file 
(since Ipopt's configure is running recursively, there are a number of 
such files).  My guess is that you would find the MKL BLAS error in 
ThirdParty/Blas/config.log.  The instructions at

https://projects.coin-or.org/BuildTools/wiki/user-troubleshooting#ProblemsDuringConfiguration

might be helpful.

A Happy New Year to all!

Andreas
