I've been packaging the rest of the COIN-OR stack (and its third-party dependencies, including this library) for Windows on the openSUSE build service, just submitted my mumps package to the official repository so it's usable without doing anything extra. See https://build.opensuse.org/request/show/285928

Fixes #1. cc @ViralBShah @dpo @lruthotto these can be updated when Mumps 5.0 is ready, I suspect it'll still need manual messiness to make shared libraries if they aren't planning on bringing their build system into this century. These binaries can be used in any other package too, though they're only the serial versions for now since none of the open-source MPI implementations support Windows at the moment.
