Build GraphViz in Windows for CI
I've recently been trying to setup CI for downstream projects (mainly pygraphviz and, by extension, NetworkX) to run the respective test suites on Windows. One of the biggest hurdles I've experienced is trying to build graphviz from source on a cloud-hosted Windows instance. It looks like there have been some recent developments e.g. in #1438 (closed) that could also be relevant for downstream projects. Is there an easy way to extract/package a subset of that procedure for use downstream? Is that a reasonable thing to do, or perhaps you have alternative approaches that are being explored? If you have any thoughts/tips in this arena please LMK - I know that the NetworkX developers would be very happy to collaborate on a solution to improve both our workflow and support for NX/pygraphviz users on windows (CC: @dschult @jarrodmillman)
