[Ipopt] Linker errors

Hi,

What about the file logging option of Ipopt?

Did you compile your application also with -MTd?
If not everything it compiled with the same option (-MT, -MTd, or no 
-MT), then things are likely to make trouble.

You can try to exclude libcmtd.lib and hope that it finds everything in 
libcmt.lib (if that is what your code uses).

Best,
Stefan
