There was an error in the Windows docker file to build extensions. There is also a linking problem only on Windows with mumps undefined references to gfortran. I added -lgfortran to the mumps cflags for Ipopt, and hopfully that will fix it. I'm guessing that mumps is being linked before fortran or maybe fortran is not linked at all.
