CMP0050

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。

Disallow add_custom_command SOURCE signatures.

CMake 2.8.12 and lower allowed a signature for add_custom_command() which specified an input to a command. This was undocumented behavior. Modern use of CMake associates custom commands with their output, rather than their input.

The OLD behavior for this policy is to allow the use of add_custom_command() SOURCE signatures. The NEW behavior for this policy is to issue an error if such a signature is used.

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。
