* Proof of concept for CMake Abseil dependency * Hooked up Abseil linking * Adding test binaries * Reverting absl::string view use added for testing. This will still be broken for automake and bazel * Adding new cmake config to dist list * Whitespace fixes and an attempt at fix for Windows Python Release (CMake version < 3.13) * Hook up LTS to windows cmake * Fix 'git cd' typo * Adding clarifying comment for fix * Adding abseil dependency to protobuf-lite too * Update submodules instead of cloning abseil-cpp * Adding explicit pointer to abseil root directory Co-authored-by: Jason Lunn <jason.lunn@gmail.com> Co-authored-by: Jorg Brown <jorg.brown@gmail.com>
