I'm surprised how little scons is mentioned in all the chatter around the announcements of Bazel, Buck, and Pants. We use it with swtoolkit and it's really slick how multiple environments can be built up. The only problem is it's slower to start building than I would like (because it has to set up the OS environment for msvc every time, which takes 400+ms). Unfortunately swtoolkit seems to be dead since a couple years ago.
