Add continuous integration support for GitHub

James E. King, III · James E. King, III · commit f9332586d9e7 · 2017-11-23T09:35:41.000-05:00
pull requests through Travis CI and Appveyor. Fix cygwin build issues. Recommend everyone use cmake to generate build environments, and consider checked-in projects or makefiles to be deprecated. The generated build will always be correct, and proven by CI. This fixes madler#162 This fixes madler#238 This fixes madler#307
