Unlike most policies, +CMake version |release| does *not* warn by default when this policy +is not set and simply uses OLD behavior. See documentation of the +:variable:`CMAKE_POLICY_WARNING_CMP0065 <CMAKE_POLICY_WARNING_CMP<NNNN>>` +variable to control the warning. + +.. include:: DEPRECATED.txt |
