Subject: Genex: Add $<LINK_LIBRARY:...>
This generator expression offers the capability, for the link step, to
decorate libraries with prefix/suffix flags and/or adding any specific flag for each
library.
Fixes: #22812, #18751, #20078, #22703

+ For example:
+

+
+ add_library(lib1 STATIC ...)
+ add_library(lib2 ...)
+ target_link_libraries(lib2 PRIVATE $<LINK_LIBRARY:whole_archive,lib1>)
+
+ This specify to use the ``lib1`` target with feature ``whole_archive`` for
+ linking target ``lib2``. The feature must have be defined by
+ :variable:`CMAKE_<LANG>_LINK_USING_<FEATURE>` variable or, if
+ :variable:`CMAKE_<LANG>_LINK_USING_<FEATURE>_SUPPORTED` is false,
+ by :variable:`CMAKE_LINK_USING_<FEATURE>` variable.
+
+ .. note::
+
+ The evaluation of this generator expression will use, for the following
+ variables, the values defined at the level of the creation of the target:
+
+ * :variable:`CMAKE_<LANG>_LINK_USING_<FEATURE>_SUPPORTED`
+ * :variable:`CMAKE_<LANG>_LINK_USING_<FEATURE>`
+ * :variable:`CMAKE_LINK_USING_<FEATURE>_SUPPORTED`

+ :prop_tgt:`LINK_LIBRARIES` or :prop_tgt:`INTERFACE_LINK_LIBRARIES` target
+ properties).
+
+ .. note::
+
+ If this expression appears in the :prop_tgt:`INTERFACE_LINK_LIBRARIES`
+ property of a target, it will be included in the imported target generated
+ by :command:`install(EXPORT)` command. It is the responsibility of the
+ environment consuming this import to define the link feature used by this
+ expression.
+
+ The ``library-list`` argument can hold CMake targets or external libraries.
+ Any ``CMake`` target of type :ref:`OBJECT <Object Libraries>` or
+ :ref:`INTERFACE <Interface Libraries>` will be ignored by this expression and
+ will be handled in the standard way.
+
+ Each target or external library involved in the link step must have only one
+ kind of feature (the absence of feature is also incompatible with any
+ feature). For example:
+
+ .. code-block:: cmake
+
+ add_library(lib1 ...)
+
+ add_library(lib2 ...)
+ target_link_libraries(lib2 PUBLIC $<LINK_LIBRARY:feature1,lib1>)
+
+ add_library(lib3 ...)
+ target_link_libraries(lib3 PRIVATE lib1 lib2)
+ # an error will be raised here because lib1 has two different features
+
+ .. note::
+
+ This expression does not guarantee that the list of specified libraries
+ will be kept grouped. So, constructs like ``start-group`` and
+ ``end-group``, as supported by ``GNU ld``, cannot be used.

+
+See also the associated variable

+features dependent from the link language.
+
+This variable will be used by :genex:`LINK_LIBRARY` generator expression if,

+:variable:`CMAKE_<LANG>_LINK_USING_<FEATURE>_SUPPORTED` is false or not set.

+
+It can contain one or three elements.
+
+::
+
+ [<PREFIX>] <LIBRARY_EXPRESSION> [<SUFFIX>]
+
+When ``<PREFIX>`` and/or ``<SUFFIX>`` are specified, they encapsulate the list
+of libraries.
+
+.. note::
+
+ Even if ``<PREFIX>`` and ``<SUFFIX>`` are specified, there is not guarantee
+ that the list of specified libraries, as part of :genex:`LINK_LIBRARY`
+ generator expression, will be kept grouped. So, constructs like
+ ``start-group`` and ``end-group``, as supported by ``GNU ld``, cannot be
+ used.
+
+``<LIBRARY_EXPRESSION>`` is used to specify the decoration for each
+library. For that purpose, the patterns ``<LIBRARY>``, ``<LINK_ITEM>``, and
+``<LIB_ITEM>`` are available:
+
+* ``<LIBRARY>`` is expanded to the library as computed by CMake.
+* ``<LINK_ITEM>`` is expanded to the same expression as if the library was
+ specified in the standard way.
+* ``<LIB_ITEM>`` is equivalent to ``<LIBRARY>`` for CMake targets and is
+ expanded to the item specified by the user for external libraries.
+
+Moreover, it is possible to have different decorations for paths (CMake targets
+and external libraries specified with absolute paths) and other items specified
+by name. For that purpose, ``PATH{}`` and ``NAME{}`` wrappers can be used.
+
+For all three elements of this variable, the ``LINKER:`` prefix can be used:
+
+ .. include:: ../command/LINK_OPTIONS_LINKER.txt
+ :start-line: 3

+Examples
+^^^^^^^^
+
+Loading a whole static library
+""""""""""""""""""""""""""""""
+
+A common need is the capability to load a whole static library. This capability
+is offered by various environments but with a specific syntax:
+
+.. code-block:: cmake
+
+ set(CMAKE_C_LINK_USING_whole_archive_SUPPORTED TRUE)
+ if(CMAKE_C_COMPILER_ID STREQUAL "AppleClang")
+ set(CMAKE_C_LINK_USING_whole_archive "-force_load <LIB_ITEM>")
+ elseif(CMAKE_C_COMPILER_ID STREQUAL "GNU"
+ AND CMAKE_SYSTEM_NAME STREQUAL "Linux")
+ set(CMAKE_C_LINK_USING_whole_archive "LINKER:--push-state,--whole-archive"
+ "<LINK_ITEM>"
+ "LINKER:--pop-state")
+ elseif(CMAKE_C_COMPILER_ID STREQUAL "MSVC")
+ set(CMAKE_C_LINK_USING_whole_archive "/WHOLEARCHIVE:<LIBRARY>")
+ else()
+ # feature not yet supported for the other environments
+ set(CMAKE_C_LINK_USING_whole_archive_SUPPORTED FALSE)
+ endif()
+
+ add_library(lib1 STATIC ...)
+
+ add_library(lib2 SHARED ...)
+ if(CMAKE_C_LINK_USING_whole_archive_SUPPORTED)
+ target_link_libraries(lib2 PRIVATE
+ $<LINK_LIBRARY:whole_archive,lib1,$<IF:$<LINK_LANG_AND_ID:C,Clang>,libexternal.a,external>>)
+ else()
+ target_link_libraries(lib2 PRIVATE lib1 external)
+ endif()
+
+CMake will generate the following link expressions:
+
+* ``Clang``: ``-force_load /path/to/lib1.a -force_load libexternal.a``
+* ``GNU``: ``-Wl,--whole-archive /path/to/lib1.a -lexternal -Wl,--no-whole-archive``
+* ``MSVC``: ``/WHOLEARCHIVE:/path/to/lib1.lib /WHOLEARCHIVE:external.lib``
+
+CMake will ensure, when possible, that ``<PREFIX>`` and ``<SUFFIX>`` are
+not repeated for each library.
+
+In case of ``Clang``, the pattern ``<LIB_ITEM>`` is used because we need to
+specify the library as defined by the user, not the name computed by CMake
+(in that case ``external``).
+
+Linking a library as weak
+"""""""""""""""""""""""""
+
+On MacOS, it is possible to link a library in weak mode (the library and all
+references are marked as weak imports), but different flags must be used for a
+library specified by path and by name. This constraint by be solved by using
+``PATH{}`` and ``NAME{}`` wrappers:
+
+.. code-block:: cmake
+
+ if (CMAKE_C_COMPILER_ID STREQUAL "AppleClang")
+ set(CMAKE_LINK_USING_weak_library "PATH{-weak_library <LIBRARY>}NAME{LINKER:-weak-l<LIB_ITEM>}")
+ set(CMAKE_LINK_USING_weak_library_SUPPORTED TRUE)
+ endif()
+
+ add_library(lib SHARED ...)
+ add_executable(main ...)
+ if(CMAKE_LINK_USING_weak_library_SUPPORTED)
+ target_link_libraries(main PRIVATE $<LINK_LIBRARY:weak_library,lib,external>)
+ else()
+ target_link_libraries(main PRIVATE lib external)
+ endif()
+
+CMake will generate the following link expression:
+``-weak_library /path/to/lib -Xlinker -weak-lexternal``
