-- -latomic is required to link hhvm
CMake Deprecation Warning at CMake/HPHPFunctions.cmake:2 (cmake_policy):
  The OLD behavior for policy CMP0026 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.

CMake Warning (dev) at hphp/hhvm/CMakeLists.txt:47 (target_sources):
  Policy CMP0076 is not set: target_sources() command converts relative paths
  to absolute.  Run "cmake --help-policy CMP0076" for policy details.  Use
  the cmake_policy command to set the policy and suppress this warning.

  An interface source of target "hhvm" has a relative path.
This warning is for project developers.  Use -Wno-dev to suppress it.
