           Summary: cmake warnings when configuring without static
                    analyzer and arcmt

           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW

When configuring llvm (with clang and compiler-rt) using

  cmake $srcdir -DCMAKE_BUILD_TYPE="RelWithDebInfo"
-DCMAKE_INSTALL_PREFIX=$installprefix -DLLVM_ENABLE_ASSERTIONS=ON
-DCLANG_ENABLE_STATIC_ANALYZER=OFF -DCLANG_ENABLE_ARCMT=OFF -GNinja

the following CMake warnings are issued (the build still seems to work fine):

-- Configuring done
CMake Warning (dev) at cmake/modules/AddLLVM.cmake:725 (add_dependencies):
  Policy CMP0046 is not set: Error on non-existent dependency in
  add_dependencies.  Run "cmake --help-policy CMP0046" for policy details.
  Use the cmake_policy command to set the policy and suppress this warning.

  The dependency target "clang-check" of target "check-all" does not exist.
Call Stack (most recent call first):
  CMakeLists.txt:605 (add_lit_target)
This warning is for project developers.  Use -Wno-dev to suppress it.
