| 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. |
