[Ipopt] compilation of 3.7.0 failed

[Stefan Vigerske]

Hi,

does it also work if you comment out the definition of log2 in
ThirdParty/Metis/metis-4.0/Lib/proto.h
and ThirdParty/Metis/metis-4.0/Lib/util.c?
That might be better than editing mathcalls.h.

You could also just build Ipopt without Metis.
