[Couenne] configuring Couenne

[Pietro Belotti]

Hi,

Ipopt, an essential component of Couenne, needs a linear system  
solver, and can use Mumps or the solvers in the HSL library. In order  
to build Couenne, you need to obtain at least one of them. Please see  
Couenne/ThirdParty/HSL/INSTALL.HSL for instructions on HSL.
