    CMakeExpandImportedTargets: Document as deprecated
    
    The module is not needed anymore for try_compile or try_run.  It cannot
    be used with CMP0022 NEW behavior due to generator expressions in
    INTERFACE_LINK_LIBRARIES, so document it as deprecated.  Whatever
    problems other than try_compile and try_run anyone tried to solve with
    this module will have to be addressed another way.

+# This module was once needed to expand imported targets to the underlying

+# and :command:`try_run` commands.  These commands now support imported
+# libraries in their ``LINK_LIBRARIES`` options (since CMake 2.8.11
+# for :command:`try_compile` and since CMake 3.2 for :command:`try_run`).
+#
+# This module does not support the policy :policy:`CMP0022` ``NEW``
+# behavior or use of the :prop_tgt:`INTERFACE_LINK_LIBRARIES` property
+# because :manual:`generator expressions <cmake-generator-expressions(7)>`
+# cannot be evaluated during configuration.
