[Ipopt] Error during Ipopt compilation using Cygwin

[Ted Ralphs]

I haven't looked closely enough either to be sure if the issue mentioned by
Austin is the one you're running into, but there are more details on this
issue listed here in case:

https://projects.coin-or.org/BuildTools/wiki/current-issues#Configuration

I might also suggest MSys2 as an alternative (perhaps less problematic)
*nix build environment on Windows.

Cheers,

Ted
