-- **sources**: 源文件列表（相对配置文件路径）；
+- **sources**: 源文件列表，应为相对当前配置文件的路径，可使用通配符。例如，`"src/*"` 会将配置文件所在目录下的 `src` 文件夹中的所有文件复制或链接到相应工程目录下的 `src` 文件夹中。
 - **target_cpu**: 目标 CPU ID[^2]；
 - **os**: 操作系统类型[^1]，必须与 BSP/Domain 匹配；
 - **language**: 编程语言，"C" 或 "C++"；
 - *bsp*: 应用所使用的 BSP 名称，若未指定则会自动创建名为 `<os>_<cpu_id>` 的 BSP/Domain.
