INTERFACE_INCLUDE_DIRECTORIES.

@ -22,10 +22,6 @@ items will populate the :prop_tgt:`SOURCES` property of
following arguments specify sources. Repeated calls for the same
``<target>`` append items in the order called.
Targets with :prop_tgt:`INTERFACE_SOURCES` may not be exported with the
:command:`export` or :command:`install(EXPORT)` commands. This limitation may be
lifted in a future version of CMake.
Arguments to ``target_sources`` may use "generator expressions"
with the syntax ``$<...>``. See the :manual:`cmake-generator-expressions(7)`
manual for available expressions. See the :manual:`cmake-buildsystem(7)`
