+Custom Transitive Properties
+----------------------------
+
+.. versionadded:: 3.30
+
+The :genex:`TARGET_PROPERTY` generator expression evaluates the above
+`build specification <Target Build Specification_>`_ and
+`usage requirement <Target Usage Requirements_>`_ properties
+as builtin transitive properties.  It also supports custom transitive
+properties defined by the :prop_tgt:`TRANSITIVE_COMPILE_PROPERTIES`
+and :prop_tgt:`TRANSITIVE_LINK_PROPERTIES` properties on the target
+and its link dependencies.
+
+For example:
+
+.. code-block:: cmake
+
+  add_library(example INTERFACE)
+  set_target_properties(example PROPERTIES
+    TRANSITIVE_COMPILE_PROPERTIES "CUSTOM_C"
+    TRANSITIVE_LINK_PROPERTIES    "CUSTOM_L"
+
+    INTERFACE_CUSTOM_C "EXAMPLE_CUSTOM_C"
+    INTERFACE_CUSTOM_L "EXAMPLE_CUSTOM_L"
+    )
+
+  add_library(mylib STATIC mylib.c)
+  target_link_libraries(mylib PRIVATE example)
+  set_target_properties(mylib PROPERTIES
+    CUSTOM_C           "MYLIB_PRIVATE_CUSTOM_C"
+    CUSTOM_L           "MYLIB_PRIVATE_CUSTOM_L"
+    INTERFACE_CUSTOM_C "MYLIB_IFACE_CUSTOM_C"
+    INTERFACE_CUSTOM_L "MYLIB_IFACE_CUSTOM_L"
+    )
+
+  add_executable(myexe myexe.c)
+  target_link_libraries(myexe PRIVATE mylib)
+  set_target_properties(myexe PROPERTIES
+    CUSTOM_C "MYEXE_CUSTOM_C"
+    CUSTOM_L "MYEXE_CUSTOM_L"
+    )
+
+  add_custom_target(print ALL VERBATIM
+    COMMAND ${CMAKE_COMMAND} -E echo
+      # Prints "MYLIB_PRIVATE_CUSTOM_C;EXAMPLE_CUSTOM_C"
+      "$<TARGET_PROPERTY:mylib,CUSTOM_C>"
+
+      # Prints "MYLIB_PRIVATE_CUSTOM_L;EXAMPLE_CUSTOM_L"
