[Ipopt] MKL and non-MKL Pardiso

[Stefan Vigerske]

Hi,

no.
Unfortunately, both Pardiso's use the same function name. When linking 
the Ipopt library, it is decided which Pardiso will be used. If both MKL 
and non-MKL Pardiso are found during configure, then during compilation, 
Ipopt believes that it will use the non-MKL Pardiso. Then there is a 
portion of hope that the linker will resolve the pardiso-function symbol 
with the one from the non-MKL Pardiso library, too.

Maybe one could change things to load the non-MKL pardiso at runtime 
(dlopen()). That should avoid some uncertainty and allow to choose 
between both Pardiso's at runtime.
