During build system +generation files would be written and then overwritten in the build +tree and could lead to strange behavior. CMake 2.6.4 and above +explicitly detect duplicate binary directories. CMake 2.6.4 always +considers this case an error. In CMake 2.8.0 and above this policy +determines whether or not the case is an error. The OLD behavior for +this policy is to allow duplicate binary directories. The NEW +behavior for this policy is to disallow duplicate binary directories +with an error. + +This policy was introduced in CMake version 2.8.0. CMake version +|release| warns when the policy is not set and uses OLD behavior. Use +the cmake_policy command to set it to OLD or NEW explicitly. |
