CMP0009

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。

FILE GLOB_RECURSE calls should not follow symlinks by default.

In CMake 2.6.1 and below, file(GLOB_RECURSE) calls would follow through symlinks, sometimes coming up with unexpectedly large result sets because of symlinks to top level directories that contain hundreds of thousands of files.

This policy determines whether or not to follow symlinks encountered during a file(GLOB_RECURSE) call. The OLD behavior for this policy is to follow the symlinks. The NEW behavior for this policy is not to follow the symlinks by default, but only if FOLLOW_SYMLINKS is given as an additional argument to the FILE command.

此方針於 CMake 版本 2.6.2 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。
