synergy 1.4.16 无法编译 - 未定义对“pthread_xxxx”的引用
synergy 1.4.16 fails to compile - undefined reference to `pthread_xxxx'
尝试在 Mint 17.1 (Rebecca) 上编译 synergy 1.4.16 时出现以下错误：

我已经尝试过相同问题的解决方案 here，但是在 src/cmd/synergyd/CMakeLists.txt 上的 target_link_libraries 末尾添加 pthread 的解决方案并没有解决我的问题，它保持不变。
我不使用预编译包的唯一原因是我需要与我的 Raspberry Pi 3 协同使用，并且通过 packge repos 提供的包具有不兼容的协同协议 - Pi 上的 1.4.16 vs Mint 17.1 上的 1.4.12，因此在每台机器上具有兼容协议的替代解决方案也足够了。
确定了一个替代解决方案：我通过（ab？）使用具有较高协议版本的协同服务器似乎 backwards-compatible 具有较旧协议版本的事实来解决这个问题，所以我编译了该版本1.8.something 我 Pi 上的 1.4.16 客户端很高兴连接，我现在可以与 Pi 共享连接到我的 Mint 的键盘和鼠标。
在 CMakeList.txt 中的项目定义后设置 CMAKE_CXX_FLAGS 使其适用于我：
首先，申报项目（先决条件检查很重要）。
项目（协同 C CXX）
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++03 -pthread")
