如果nmake在批处理期间失败，则返回错误并发送电子邮件

首先，没有可用的本地命令可让您发送电子邮件。您可以使用Windows脚本（VBScript或JScript）来编写脚本CDO.Message。将Windows脚本宿主合并到批处理脚本中的最简单的方法是使用混合脚本。

您可以使用条件执行来触发发送电子邮件功能（如果存在）cmake或nmake以非零状态退出。

这是一个入门的示例框架。请注意，这未经测试，可能已损坏。但无论如何，它至少应该为您提供一个起点。

（另请注意，我更换了rm -R *与原生Windows命令，并输出cmake和nmake被重定向到%temp%\build.log包含到，如果需要的电子邮件。如果你想回显到控制台以及输出，你可能会使用tee -a，如果您有Cygwin的或安装了gnuwin32或类似产品；或者可能包含此脚本模仿。）
