6Do not add flags to export symbols from executables without
7the :prop_tgt:`ENABLE_EXPORTS` target property.
8
9CMake 3.3 and below, for historical reasons, always linked executables
10on some platforms with flags like ``-rdynamic`` to export symbols from
11the executables for use by any plugins they may load via ``dlopen``.
12CMake 3.4 and above prefer to do this only for executables that are
13explicitly marked with the :prop_tgt:`ENABLE_EXPORTS` target property.
14
15The ``OLD`` behavior of this policy is to always use the additional link
16flags when linking executables regardless of the value of the
17:prop_tgt:`ENABLE_EXPORTS` target property.
18
19The ``NEW`` behavior of this policy is to only use the additional link
20flags when linking executables if the :prop_tgt:`ENABLE_EXPORTS` target
21property is set to ``True``.
22
23This policy was introduced in CMake version 3.4.  Unlike most policies,
24CMake version |release| does *not* warn by default when this policy
25is not set and simply uses ``OLD`` behavior.  See documentation of the
26:variable:`CMAKE_POLICY_WARNING_CMP0065 <CMAKE_POLICY_WARNING_CMP<NNNN>>`
27variable to control the warning.
