 cmake-policies(7)
 *****************
 
+Policies in CMake are used to preserve backward compatible behavior
+across multiple releases.  When a new policy is introduced, newer CMake
+versions will begin to warn about the backward compatible behavior.  It
+is possible to disable the warning by explicitly requesting the OLD, or
+backward compatible behavior using the cmake_policy() command.  It is
+also possible to request NEW, or non-backward compatible behavior for a
+policy, also avoiding the warning.
+
+The cmake_minimum_required() command does more than report an error if
+a too-old version of CMake is used to build a project.  It also sets
+all policies introduced in that CMake version or earlier to NEW
+behavior.
+
+The CMAKE_MINIMUM_REQUIRED_VERSION variable may also be used to
+determine whether to report an error on use of deprecated macros or
+functions.
