Prefer files from the CMake module directory when including from there.

Starting with CMake 2.8.4, if a cmake-module shipped with CMake (i.e.
located in the CMake module directory) calls :command:`include` or
:command:`find_package`, the files located in the CMake module directory are
preferred over the files in :variable:`CMAKE_MODULE_PATH`.  This makes sure
that the modules belonging to CMake always get those files included which
they expect, and against which they were developed and tested.  In all
other cases, the files found in :variable:`CMAKE_MODULE_PATH` still take
precedence over the ones in the CMake module directory.  The ``OLD``
behavior is to always prefer files from CMAKE_MODULE_PATH over files
from the CMake modules directory.

This policy was introduced in CMake version 2.8.4.  CMake version
|release| warns when the policy is not set and uses ``OLD`` behavior.  Use
the :command:`cmake_policy` command to set it to ``OLD`` or ``NEW`` explicitly.
