Hi, I'm using the monorepo @ 581445d4e6037de8587053c4b2030a01c7541fda

When trying to build the second stage (make all) using previously compiled
clang of the same repo commit, libcxx_fuzzer fails to compile due to a llvm
error:

CMake Deprecation Warning at CMakeLists.txt:14 (cmake_policy):
  The OLD behavior for policy CMP0051 will be removed from a future version
  of CMake.
  The cmake-policies(7) manual explains that the OLD behaviors of all
  policies are deprecated and that a policy should be set to OLD only under
  specific short-term circumstances.  Projects should be ported to the NEW
  behavior and not rely on setting a policy to OLD.
