Meta: Add a CMake function to download remote files during the build
This function will handle download failures. It doesn't support hashing
for integrity yet, but if the download times out or otherwise fails, the
build itself will fail. But default, file(DOWNLOAD) in CMake doesn't
fail the build; we must pass in and check a STATUS variable.
