.. versionadded:: 3.24
:prop_tgt:`LINK_LIBRARIES` supports the :genex:`$<LINK_ONLY:...>`
generator expression.
CMake 3.23 and below documented the :genex:`$<LINK_ONLY:...>` generator
expression only for use in :prop_tgt:`INTERFACE_LINK_LIBRARIES`.
When used in :prop_tgt:`LINK_LIBRARIES`, the content guarded inside
:genex:`$<LINK_ONLY:...>` was always used, even when collecting non-linking
usage requirements such as :prop_tgt:`INTERFACE_COMPILE_DEFINITIONS`.
CMake 3.24 and above prefer to support :genex:`$<LINK_ONLY:...>`, when
used in :prop_tgt:`LINK_LIBRARIES`, by using the guarded content only
for link dependencies and not other usage requirements. This policy
provides compatibility for projects that have not been updated to
account for this change.
The ``OLD`` behavior for this policy is to use :prop_tgt:`LINK_LIBRARIES`
content guarded by :genex:`$<LINK_ONLY:...>` even for non-linking
usage requirements. The ``NEW`` behavior for this policy is to to use
the guarded content only for link dependencies.
This policy was introduced in CMake version 3.24. Use the
:command:`cmake_policy` command to set this policy to ``OLD`` or ``NEW``
explicitly. Unlike many policies, CMake version |release| does *not*
warn when this policy is not set, and simply uses ``OLD`` behavior.
