Mac平台CMake项目链接Optick时遇UTF-8无效错误求助

我有一个依赖多个第三方库的跨平台CMake项目，Windows上编译构建正常，但在Mac平台用Ninja编译时，链接Optick环节出现如下错误：

该错误出现在OptickCore目标生成的所有目标文件上。

CMake配置信息 #

项目通过CMake生成，配置过程正常：

项目配置细节 #

• 在CMake脚本中，通过target_link_libraries以PUBLIC方式链接OptickCore
• 将Optick的CMakeLists.txt添加为子目录

文件编码排查 #

• 源码文件编码为us-ascii：

matthewloveday@192 src % file -I optick_capi.cpp
optick_capi.cpp: text/x-c; charset=us-ascii

• 目标文件编码为二进制：

matthewloveday@192 src % file -I optick_capi.cpp.o     
optick_capi.cpp.o: application/x-mach-binary; charset=binary

从未遇到过此类错误，不知从何入手，恳请各位提供帮助！
