c-无法在windows上生成libevent

Question

所以我一直在尝试在Windows上构建libevent。然而，当我运行nmake MakeFile.nmake时，它一直给我以下输出。。。

Stop.

它似乎找不到某些文件。所以我找到了winsock2.h和其他文件所在的目录，并在这些文件中添加了一个环境变量，但我仍然会收到同样的错误。我还注意到，在我的系统上实际上找不到sys/types.h和limites.h。如果有人能帮我找出这个问题的原因，我将不胜感激。谢谢

更新：因此，我已经确定了系统上所需的所有文件的位置，并尝试将环境变量添加到适当的目录中，但是，当我运行nmake时，仍然找不到它们。

libevent README.md文件不建议使用nmake。它指出你使用CMake，而现有的Makefile.nake在顶部有一条大评论，暗示它可能不起作用。因此，安装cmake(您可以使用Chocolatey的'choco-install-cmake'(，然后按照文档中的说明运行命令。

mkdir build
cmake -DEVENT__DISABLE_OPENSSL=ON ..
cmake --build .

这对我使用Visual Studio 2017和分支版本2.1.8-stable的git checkout起到了作用。我添加了禁用openssl选项，因为没有这个选项它就失败了，我不想花时间单独安装它。
