我正在尝试将嵌入式 gcc arm- 项目转换为使用 ARMClang 而不是 GCC。我的重点是使用 CMake 自动生成生成文件的任务，但我不明白为什么我不能强制执行链接器标志，并且在构建过程中总是出现以下错误

[ 96%] 构建 ASM 对象 CMakeFiles/CLION-f103-armclang.elf.dir/startup/startup_stm32f103xb.o 致命错误：A9912E：未选择 --cpu

我的 CMakeLists.txt 文件的内容如下

首先，要使脚本正确构建和链接，CMakeLists.txt 文件需要进行哪些更改！？其次，如何使链接器输出标志看起来尽可能地遵循。

--cpu Cortex-M3 -g

--list *.lst
--xref -o stm32f103rbt6-LCD-CubeMX\*.o

非常感谢任何帮助
