[Ipopt] Lapack and Blas installation issue

[Stefan Vigerske]

Hi,

it's also in the Ipopt installation instructions at
https://coin-or.github.io/Ipopt/INSTALL.html#SYSTEMPACKAGES_MSYS

That should work when using GCC from MinGW as compiler.
I can imagine that this wouldn't be sufficient when using MS or Intel 
compilers. Having the Intel MKL installed and in $LIB would be one way 
to provide a Blas+Lapack then.

Note that there are also some builds for Windows available under the 
links mentioned in the README.md 
(https://github.com/coin-or/Ipopt#getting-started).
