如何为zeromq / cppzmq启用DRAFT API以在Windows上使用vcpkg进行构建？

使用vcpkg，在为ZMQ_BUILD_DRAFT_API和zeromq启用cppzmq之后。构建失败，并出现以下错误

如何通过vcpkg启用DRAFT API？

build zeromq failed-installation vcpkg

已解决the help from the 0MQ github community：我使用了错误的开关。

这里必须是-DENABLE_DRAFTS=ON。 ZMQ_BUILD_DRAFT_API是预处理程序定义，但CMake选项称为ENABLE_DRAFTS。

最重要的是，预处理器ZMQ_BUILD_DRAFT_API仍必须在VS项目中定义。

我希望这样的信息可以更容易查找。
