CMP0065 ------- Do not add flags to export symbols from executables without the :prop_tgt:`ENABLE_EXPORTS` target property. CMake 3.3 and below, for historical reasons, always linked executables on some platforms with flags like ``-rdynamic`` to export symbols from the executables for use by any plugins they may load via ``dlopen``. CMake 3.4 and above prefer to do this only for executables that are explicitly marked with the :prop_tgt:`ENABLE_EXPORTS` target property. The ``OLD`` behavior of this policy is to always use the additional link flags when linking executables regardless of the value of the :prop_tgt:`ENABLE_EXPORTS` target property. The ``NEW`` behavior of this policy is to only use the additional link flags when linking executables if the :prop_tgt:`ENABLE_EXPORTS` target property is set to ``True``. This policy was introduced in CMake version 3.4. 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
