[BuildTools] [Ipopt] Difficulties with Ipopt 3.9.1 on Linux (Ubuntu 10.04)

[Stefan Vigerske]

Hi,

it will be difficult to change the libdir within one stable branch, 
since people who are expecting only bugfixes when going from, e.g., 
3.9.2 to 3.9.3, could be confused by the changed location of the 
libraries and, more important, uninstalling the previously installed 
libraries does not work.
So it looks like for Ipopt 3.9.x, we will stay with $libdir/coin and 
$libdir/coin/ThirdParty.

However, attached you find a patch for Ipopt 3.9.2 that, if applied 
before configure, changes the directory for the libraries to $libdir 
again. But note that the extras (examples, AsNMPC, tutorial, ...) may 
not work then.
