Thanks for the advice. I added the third party code as you suggested. The get scripts
did not work because I had issues with wget and also some of the file names in the
scripts do not match the files that were downloaded. I had to manually implement some
of the steps in the get scripts.

After running configure -C, I get a different error.

checking whether LAPACK is already available with BLAS library... no
checking whether -llapack has LAPACK... yes
configure: Checking for Harwell subroutine library
checking whether MUMPS is available... no
configure: error: "No linear solver (such as MUMPS) available.  You need to provide
at least one."
configure: error: /bin/sh './configure' failed for Ipopt

There is nothing listed under MUMPS in the cygwin package manager. How do I go about
resolving this?
