 Specify a strategy for ordering a target's direct link dependencies
 on linker command lines.
 
-See the :variable:`CMAKE_LINK_LIBRARIES_STRATEGY` variable for details
-and supported values.  This property is initialized by the value of that
-variable when a target is created.
+CMake generates a target's link line using its :ref:`Target Link Properties`.
+In particular, the :prop_tgt:`LINK_LIBRARIES` target property records the
+target's direct link dependencies, typically populated by calls to
+:command:`target_link_libraries`.  Indirect link dependencies are
+propagated from those entries of :prop_tgt:`LINK_LIBRARIES` that name
+library targets by following the transitive closure of their
+:prop_tgt:`INTERFACE_LINK_LIBRARIES` properties.  CMake supports multiple
+strategies for passing direct and indirect link dependencies to the linker.
+
+Consider this example for the strategies below:
+
+.. code-block:: cmake
+
+  add_library(A STATIC ...)
+  add_library(B STATIC ...)
+  add_library(C STATIC ...)
+  add_executable(main ...)
+  target_link_libraries(B PRIVATE A)
+  target_link_libraries(C PRIVATE A)
+  target_link_libraries(main PRIVATE A B C)
+
+The supported strategies are:
+
+``PRESERVE_ORDER``
+  Entries of :prop_tgt:`LINK_LIBRARIES` always appear first and in their
+  original order.  Indirect link dependencies not satisfied by the
+  original entries may be reordered and de-duplicated with respect to
+  one another, but are always appended after the original entries.
+  This may result in less efficient link lines, but gives projects
+  control of ordering among independent entries.  Such control may be
+  important when intermixing link flags with libraries, or when multiple
+  libraries provide a given symbol.
+
+  This is the default.
+
+  In the above example, this strategy computes a link line for ``main``
+  by starting with its original entries ``A B C``, and then appends
+  another ``A`` to satisfy the dependencies of ``B`` and ``C`` on ``A``.
+  The final order is ``A B C A``.
+
+``REORDER``
+  Entries of :prop_tgt:`LINK_LIBRARIES` may be reordered, de-duplicated,
+  and intermixed with indirect link dependencies.  This may result in
+  more efficient link lines, but does not give projects any control of
+  ordering among independent entries.
+
+  In the above example, this strategy computes a link line for ``main``
+  by re-ordering its original entries ``A B C`` to satisfy the
+  dependencies of ``B`` and ``C`` on ``A``.
+  The final order is ``B C A``.
+
+.. note::
+
+  Regardless of the strategy used, the actual linker invocation for
+  some platforms may de-duplicate entries based on linker capabilities.
+  See policies :policy:`CMP0156` and :policy:`CMP0179`.
+
+This property is initialized by the value of the
+:variable:`CMAKE_LINK_LIBRARIES_STRATEGY` variable if it is set when a
+target is created.
