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.
