CMake Deprecation Warning

CMake Deprecation Warning at cmake/for_clients.cmake:15 (CMAKE_POLICY):

  The OLD behavior for policy CMP0007 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.
