Added in version 3.13.
Relative paths not allowed in LINK_DIRECTORIES target property.
CMake 3.12 and lower allowed the LINK_DIRECTORIES directory
property to contain relative paths. The base path for such relative
entries is not well defined. CMake 3.13 and later will issue a
FATAL_ERROR if the LINK_DIRECTORIES target property
(which is initialized by the LINK_DIRECTORIES directory property)
contains a relative path.
The OLD behavior for this policy is not to warn about relative paths
in the LINK_DIRECTORIES target property. The NEW behavior for
this policy is to issue a FATAL_ERROR if LINK_DIRECTORIES
contains a relative path.
This policy was introduced in CMake version 3.13.
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.
