I've fixed some errors(e.g. Prefix "rules_foreign_cc-master" was given, but not found in the archive.) from BUILD and WORKSPACE, but still hit below errors: "no such package '@@bazel_tools//platforms': BUILD file not found in directory 'platforms' of external repository @@bazel_tools. Add a BUILD file to a directory to mark it as a package." ...

I also tried to build with CMAKE but hit other dependency related errors(e.g. libevent...) , still investigating on it.

In general, I think this project is fully unusable now untill all these dependency issues to be fixed.
