[Feature request] Conan recipe to build C++ client and publication to conan-center

[Conan.io](https://conan.io/) is a popular C++ package manager. It would be very handy to have a conan recipe to build the C++ client. It would make it easy to build even on Windows, even with MSVC.
Ultimately, you could pre-build conan packages for various platforms and compilers and publish them to [conan-center](https://bintray.com/conan/conan-center) so that it's easy to include the client lib in a conan-enabled project.

首先檢視儲存庫的 C++ 建置設定與 Conan recipe 的需求。確定用戶端所需的套件中繼資料、平台與編譯器組合，以及發佈至 conan-center 的流程。完成標準是：Conan recipe 能夠建置 C++ 用戶端，包括在使用 MSVC 的 Windows 上建置，且套件已準備好發佈至 conan-center。
