CMP0065

警告

該方針的 OLD 行為已在 CMake 版本 4.0 中移除。該方針必須透過呼叫 cmake_minimum_required() 或 cmake_policy() 設定為 NEW。

在 3.4 版被加入.

Do not add flags to export symbols from executables without the 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 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 ENABLE_EXPORTS target property.

The NEW behavior of this policy is to only use the additional link flags when linking executables if the ENABLE_EXPORTS target property is set to True.

此方針於 CMake 版本 3.4 中引入。在 CMake 版本 4.0 移除之前，它可以透過 cmake_policy() 或 cmake_minimum_required() 設定。如果未設定，CMake did not warn by default，並使用 OLD 行為。

See documentation of the CMAKE_POLICY_WARNING_CMP0065 variable to control the warning in CMake versions before 4.0.
