配置生成代码的编译过程

自定义生成源代码的编译和链接

对于某些应用，您可能要控制在 C/C++ 源代码生成之后、编译之前发生的编译过程的各个方面。要从 MATLAB^® 代码内指定其他编译文件和标志，请使用 coder.updateBuildInfo 函数。或者，在工作区中创建一个 RTW.BuildInfo 对象，并使用关联的对象函数来指定编译选项。当您处理外部代码集成或有多个使用相同编译信息的函数时，请使用 coder.ExternalDependency 类自定义编译过程。

使用 target 命名空间中的类来管理目标硬件和编译工具信息。例如，为代码生成注册新目标硬件，为外部模式和处理器在环 (PIL) 仿真设置目标连接，或为在开发计算机上编译生成的代码创建自定义 CMake 工具链定义。
