Build failure

[kination]

Hello~
I'm a beginner in this project. I just faced an error while build:

  Compiling actix v0.7.9
   Compiling snow v0.4.2
   Compiling exonum_sodiumoxide v0.0.20
error: failed to run custom build command for `exonum v0.10.2 (/Users/kwangin/workspace/exonum/exonum)`
process didn't exit successfully: `/Users/kwangin/workspace/exonum/target/debug/build/exonum-a38683bcef37b8fd/build-script-build` (exit code: 101)
--- stdout
cargo:protos=/Users/kwangin/workspace/exonum/exonum/src/proto/schema/exonum

--- stderr
thread 'main' panicked at 'protoc: Custom { kind: NotFound, error: StringError("failed to spawn `\"protoc\" \"--version\"`: No such file or directory (os error 2)") }', libcore/result.rs:1009:5
...

Is there somebody know about this?

My env:

MacOS: 10.14
Rust: 1.31

@djKooks Hello. You need to install protobuf compiler and dev libraries. On Mac, it's enough to install zprotobuf package using brew. On Ubuntu you'll need protobuf-compiler and libprotobuf-dev packages.

We'll update our installation instructions soon.

@vitvakatu thanks! Official docs didn't comment about protobuf(seems updated in newest version), so I missed it.
