It would make sense to support struct elements and enum elements, but that has not been implemented. Char arrays are more controversial due to verification and zero termination and are also not supported. Arrays are aligned to the size of the first field and are equivalent to repeating elements...

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...
