[Ipopt] Question about static libraies.

[Tae-Hyuk Ahn]

Hi Stefan,

Yep, I forgot to reorder the linker flags before. After I reorder, I
am still getting errors.

g++ -fopenmp -static utils.o parse_config.o gereme_config.o
gereme_core.o gereme_ipopt_main.o gereme_ipopt_nlp.o libipopt.a
libipoptamplinterface.a libcoinasl.a libcoinblas.a libcoinlapack.a
libcoinmetis.a libcoinmumps.a libipopt.a libipoptamplinterface.a -o
gereme-solve-model

The order of static archives is also make error? The errors look like this:
