CMP0038

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。

Targets may not link directly to themselves.

CMake 2.8.12 and lower allowed a build target to link to itself directly with a target_link_libraries() call. This is an indicator of a bug in user code.

The OLD behavior for this policy is to ignore targets which list themselves in their own link implementation. The NEW behavior for this policy is to report an error if a target attempts to link to itself.

此方針於 CMake 版本 3.0 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 warned，並使用 OLD 行為。
