The CMake devteam is very responsive about bug reports. They will
certainly appreciate your bug report, no patch required.

I'm seeing a failure related to circular library references while
building LLVM with CMake and MSYS. This didn't happen on the
past. Building with the configure script works, so it seems something
related to CMake. Do you have any insight on this?

Apart from the circular library references mentioned above, CMake works
fine with MSYS for me (well, the generated makefiles doesn't work with
parallel make (-j x) but that's another issue).
