Input directories must have CMakeLists.txt
.
CMake versions before 2.8 silently ignored missing CMakeLists.txt
files in directories referenced by add_subdirectory()
or subdirs()
,
treating them as if present but empty. In CMake 2.8.0 and above this
cmake_policy()
determines whether or not the case is an error.
The OLD
behavior for this policy is to silently ignore the problem.
The NEW
behavior for this policy is to report an error.
This policy was introduced in CMake version 2.8.0.
It may be set by cmake_policy()
or cmake_minimum_required()
.
If it is not set, CMake warns, and uses OLD
behavior.
Note
The OLD
behavior of a policy is
deprecated by definition
and may be removed in a future version of CMake.
