Every policy's documentation has a paragraph on what version of CMake introduced it, how to set the policy, and whether CMake warns if the policy is not set. The wording of this paragraph has diverged across policies over time. Factor the paragraph out into a standard advice document included by every policy.

``CMAKE_BACKWARDS_COMPATIBILITY`` should no longer be used.
|
|
|
|
The behavior is to check ``CMAKE_BACKWARDS_COMPATIBILITY`` and present
|
|
it to the user. The ``NEW`` behavior is to ignore
|
|
CMAKE_BACKWARDS_COMPATIBILITY completely.
|
|
|
|
In CMake 2.4 and below the variable ``CMAKE_BACKWARDS_COMPATIBILITY`` was
|
|
used to request compatibility with earlier versions of CMake. In
|
|
CMake 2.6 and above all compatibility issues are handled by policies
|
|
and the :command:`cmake_policy` command. However, CMake must still check
|
|
``CMAKE_BACKWARDS_COMPATIBILITY`` for projects written for CMake 2.4 and
|
|
below.
