Hmm, I believe that with `set_property(GLOBAL PROPERTY GLOBAL_DEPENDS_NO_CYCLES ON)`, CMake should have reported the error before ninja build is run though.

Because I can't reproduce the issue, I want to find the exact reason causing the dependency cycle. Otherwise the `build.ninja` file may contain useful information at 

```build.ninja
#############################################
# Link the shared library lib/libclangFrontend.so.22.0git
...
```

Otherwise the GraphViz Dot files might show why the cycle is caused.
