title: Convert Makefile to Bazel?
body: <p>Bazel says that best practice is to not use binary dependencies, <a href="https://docs.bazel.build/versions/master/best-practices.html#depending-on-binaries" rel="nofollow noreferrer">but to build the dependency from source using Bazel</a>. I have a dependency - <a href="https://github.com/dmlc/xgboost" rel="nofollow noreferrer">xgboost</a> - that builds using Makefiles, and I was wondering what the canonical strategy is to convert Makefiles to Bazel - as well as if there are any standard tools that programmers use as part of the conversion.</p>
