CMP0152

New 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. Use the cmake_policy() command to set it to OLD or NEW explicitly.

Note

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