# We manage the build/ folder and its Makefiles as a submodule.
# The first time `make` is run, the includes of build/*.mk files will
# all fail, and this target will be run. The next time, the default as defined
# by the includes will be run instead.

# Linux machines to use that directory as the build cache as well. We should
# adjust this behavior in the build submodule because it is also causing Linux
# users to duplicate their build cache, but for now we just make it easier to
# identify its location in CI so that we cache between builds.
