[Ipopt] compiling JIPOPT

[Tony Kelman]

For --with-pic to work properly, Jipopt would need to be be calling the C++ 
compiler through libtool (--tag=CXX --mode=compile) when it builds jipopt.o. 
It doesn't look like that's the case in 
Ipopt/contrib/JavaInterface/Makefile.in.

A workaround should be to add another configure flag "ADD_CXXFLAGS=-fPIC"

Hi,

you can try running configure with the option --with-pic.
