1CMP0014 2------- 3 4Input directories must have ``CMakeLists.txt``. 5 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. 16 17.. include:: DEPRECATED.txt 18
