[Ipopt] error message involving libiomp5mt.lib

[Frank Kampas]

While running ipopt of one of my computers, I got an error message
"initializing libiomp5mt.lib  but found libiomp5md.dll already..."
The problem went away when I set the environment variable
KMP_DUPLICATE_LIB_OK = TRUE, as suggested by the error message.
The message ended with an Intel support web site as a source of more 
information.
This is puzzling since I compiled my code using Visual Studio 10, although I
do have Intel compilers on the computer.  The problem did not occur
for small problems, only for problems over a certain size.

Can anyone shed some light on this?

Thanks
