Previously REAL_PATH would collapse paths before resolving any symlinks so if `..` crossed a symlink the output from `REAL_PATH` would be wrong. It looked like REAL_PATH did this by mistake since it was a side-effect of ensuring we had an absolute path before resolving symlinks.

:command:`file(REAL_PATH)` resolves symlinks before collapsing ../ components.
|
|
|
|
In CMake 3.27 and below, :command:`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
|
|
:command:`cmake_policy` command to set it to ``OLD`` or ``NEW`` explicitly.
