CMP0152

Added in version 3.28.

file(REAL_PATH) resolves symlinks before collapsing ../ components.

In CMake 3.27 and below, file(REAL_PATH) collapsed any ../ components in a path before resolving symlinks. This produced incorrect results when the ../ collapsed away a symlink.

The OLD behavior for this policy is to collapse ../ components before resolving symlinks. The NEW behavior for this policy is to resolve all symlinks before collapsing ../ components.

This policy was introduced in CMake version 3.28. It may be set by cmake_policy() or cmake_minimum_required(). If it is not set, CMake warns, and uses OLD behavior.

Note

The OLD behavior of a policy is deprecated by definition and may be removed in a future version of CMake.
