It will build you a shared library that Ipopt can load dynamically at 
runtime, if you specify using ma77 or ma86 as linear solver.
This should already work with Ipopt 3.10.2.

The easiest to do this is to checkout Ipopt-trunk via
  svn co https://projects.coin-or.org/svn/Ipopt/trunk Ipopt-trunk
and to follow the instructions in ThirdParty/HSL/README.
