c++ - 执行安装 Socket.IO C++ 客户端的步骤 3 时收到错误

Question

我想从“https://github.com/socketio/socket.io-client-cpp”安装 Socket.IO C++ 客户端，但是按照“https://github.com/socketio/”的步骤我遇到了一些困难socket.io-client-cpp/blob/master/INSTALL.md”。我已成功安装 boost 版本 1_73_0（第 1 步）并运行第 2 步。第 3 步遇到一些困难。运行时cmake -DBOOST_ROOT:STRING=/Users/Home/Documents/boost_1_73_0 -DBOOST_VER:STRING=1.73.0 ./ 收到此错误：

我的环境是 mac，我安装了 boost，/Users/Home/Documents/boost_1_73_0而 Socket.IO C++ Client 是/Users/Home/Documents/GitHub/socket.io-client-cpp

我还安装了boost的静态版本./b2 link=static,shared

如果您让我知道出了什么问题，我将不胜感激。我也尝试BOOST_LIBRARYDIR过，但没有帮助。我对编程很陌生，所以如果你的答案尽可能简单，我将不胜感激。
