            Bug ID: 45571
           Summary: Recent change broke cmake with CMake Error: The
                    inter-target dependency graph contains the following
                    strongly connected component (cycle):
           Product: Build scripts
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: release blocker
          Priority: P
         Component: cmake
          Assignee: unassignedbugs at nondot.org
          Reporter: sylvestre at debian.org
                CC: llvm-bugs at lists.llvm.org

CMake Error: The inter-target dependency graph contains the following strongly
connected component (cycle):
  "LLVMLTO" of type STATIC_LIBRARY
    depends on "Polly" (weak)
    depends on "LLVM" (weak)
  "LLVM" of type SHARED_LIBRARY
    depends on "LLVMLTO" (weak)
    depends on "Polly" (weak)
  "Polly" of type STATIC_LIBRARY
    depends on "LLVM" (weak)
At least one of these targets is not a STATIC_LIBRARY.  Cyclic dependencies are
allowed only among static libraries.
CMake Generate step failed.  Build files cannot be regenerated correctly.
