[Ipopt] Ipopt with statically linked MKL

[Stefan Vigerske]

Hi,

when doing static linking with gcc, the order of libraries on the 
command line is important.
Maybe there is somewhere a bug that leads having the mkl libs before the 
ipopt lib on the linker line. It's difficult to say without seeing the 
actual linker line.
You may also try configuring with --disable-pkg-config. That rules out 
one possible source for reordering of linker flags.

Hope that helps,
Stefan
