项目里用CMake，当引入Client-framework以后，发现Qt6的包引用了Qt6RemoteObjects_debug库，启动失败。

这个文件只在Qt/lib下有，Frameworks/Debug是对Frameworks/Release的引用。

所以想找是哪里引入这个_debug的，以前版本没有引用。

通过比对，发现是

/Users/conanchen/client-delivery/3P/QT/6.2.40/mac64_tls/lib/cmake/Qt6RemoteObjects/Qt6RemoteObjectsTargets-debug.cmake

当这个删除后就正常了，尝试刻意把这个改错，它也不报错。

通过调试CMake源码

set_property(TARGET Qt6::RemoteObjects APPEND PROPERTY IMPORTED_CONFIGURATIONS DEBUG)

set_target_properties(Qt6::RemoteObjects PROPERTIES

IMPORTED_LOCATION_DEBUG "${_IMPORT_PREFIX}/lib/QtRemoteObjects.framework/Versions/A/QtRemoteObjects_debug"

IMPORTED_SONAME_DEBUG "@rpath/QtRemoteObjects.framework/Versions/A/QtRemoteObjects_debug"

)

所以断点打在cmListFile::ParseFile,上条件断点，可以判断出加载这个文件。

strstr(filename, "Qt6RemoteObjects") != 0

从call stack上cmState::AddBuiltinCommand，对应的参数，可以找到具体的引用行数。

再向上bool cmMakefile::ReadDependentFile(const std::string& filename,

bool noPolicyScope)

可以找到哪个call导致引用这个-debug.cmake文件。

综合第三点和第二点，第三点给出文件，第二点给出行号，就是上面的

/Users/conanchen/client-delivery/3P/QT/6.2.40/mac64_tls/lib/cmake/Qt6RemoteObjects/Qt6RemoteObjectsTargets.cmake

第94行

get_filename_component(_DIR "${CMAKE_CURRENT_LIST_FILE}" PATH)

file(GLOB CONFIG_FILES "${_DIR}/Qt6RemoteObjectsTargets-*.cmake")

foreach(f ${CONFIG_FILES})

include(${f})

endforeach()

这里模糊查找，所以也是为什么删掉也不报错。把里面内容写错，不知道为什么也不报错，暂时没理解。

经过再次验证，由于有cache，改错，从0开始，这里会报错。
