现在我们已经收集了足够的信息,可以开始讨论 CMake 的核心功能:构建项目。在 CMake 中,一个项目包含管理将我们的解决方案带入生活的所有源文件和配置。配置从执行所有检查开始:目标平台是否受支持,是否拥有所有必要的依赖项和工具,以及提供的编译器是否工作并支持所需功能。 完成后,CMake 将为我们的选择构建工具生成...
然而,程序员就该担负职责以保证所有值都处在要求的范围内以及值不是被无意复制的。 enumcolour{red =3, blue, green, yellow =5} ;/* not compliant *//* green and yellow represent the same value – this is duplication */enumcolour{red =3, blue =4, green =5, yellow =5};/* compliant */...
