We check them out from a git tag, so this *should* be a noop. However, cmake seems to want to rebuild these dependencies every time you run make as it assumes the dependency *might* have been updated. (In practice, this isn't completely awful, as make notices the files haven't changed, so files don't actually get recompiled. But the configure step is still re-run and all the files still need to be rescanned.) Skipping the update step speeds up the build considerably. On my linux box, running: cmake .. && make -j && time make -j takes ~8.5s prior to this CL and ~6.5 afterwards. (6s is used by the test suite.) The upcoming protobuf addition would otherwise have made this much worse. (It takes a long time to ./configure.)
