4Input directories must have ``CMakeLists.txt``.

6CMake versions before 2.8 silently ignored missing ``CMakeLists.txt``
7files in directories referenced by :command:`add_subdirectory` or  :command:`subdirs`,
8treating them as if present but empty.  In CMake 2.8.0 and above this
9:command:`cmake_policy` determines whether or not the case is an error.
10The ``OLD`` behavior for this policy is to silently ignore the problem.
11The ``NEW`` behavior for this policy is to report an error.
12
13This policy was introduced in CMake version 2.8.0.  CMake version
14|release| warns when the policy is not set and uses ``OLD`` behavior.  Use
15the :command:`cmake_policy` command to set it to ``OLD`` or ``NEW`` explicitly.
