# The format for the deps below is the following:
# (target_folder, source_url, sha1, target_platform)
# |source_url| can be either a git repo or a http url.
# If a git repo, |sha1| is the committish that will be checked out.
# If a http url, |sha1| is the shasum of the original file.
# If the url is a .zip or .tgz file it will be automatically deflated under
# |target_folder|, taking care of stripping the root folder if it's a single
# root (to avoid ending up with buildtools/protobuf/protobuf-1.2.3/... and have
# instead just buildtools/protobuf).
# |target_platform| is either 'darwin', 'linux' or 'all' and applies the dep
# only on the given platform

# Dependencies required to build code on the host or when targeting desktop OS.
