Question

我要构建以下项目：https://github.com/reo7sp/tgbot-cpp

我得到以下错误：https://imgur.com/S9kgWyv

Makefile第1部分：https://imgur.com/O222bJR

Makefile第2部分：https://imgur.com/i68QLdC

现在，我认为我需要zlib，openssl和boost。卷毛似乎是可选的。

什么是“线程”？

... LIBRARY_DEBUG和... LIBRARY_RELEASE有什么区别？

LIB和SSL在GUI中是什么意思？这些“库”在生成文件中没有提到吗？

我已经绝望了好几天。请帮帮我。

错误：

原来，我需要为OpenSSL，ZLib，Boost和curl设置一些系统变量。对于Zlib，只需执行相同的过程即可。 drescherjm是一个巨大的帮助。所以谢谢！
