Windows 链接到 libcurl_a.lib

Question

我按照 curl/winbuild 目录中将 libcurl 构建为静态库的说明构建了 libcurl。它吐出一个 libcurl_a.lib，一个 .h 文件的集合，我将它们移动到我立即添加到 PATH 的文件夹中。然后我尝试使用命令

构建我的程序

cl (*my source files*) /IC:/PATH_addon/include libcurl_a.lib Ws2_32.lib Wldap32.lib /DCURL_STATICLIB /link /LIBPATH:C:/PATH_addon/lib

注：

我正在从命令行构建，因为代码不是用 IDE 或本机
C:/PATH_addon/ 是一个文件夹，我将所有需要链接到路径的东西转储到路径（它链接到我的路径），这样我就不会污染默认路径，或者我的 system32 文件夹

但是当我运行命令时，它告诉我有 12 个未解析的符号：

为什么这些符号无法解析，有没有办法解决这个问题？

解决方案（部分感谢不可思议的@Hans Passant）：

添加 /NODEFAULTLIB:LIBCMT 标志修复了问题并允许成功编译和执行。
