   in an :command:`include directory <target_include_directories>`).
   Also it ensures that ``moc`` output files will compile correctly when the

-  The ``moc`` path prefix generation behavior can be configured by setting
-  the new :variable:`CMAKE_AUTOMOC_PATH_PREFIX` variable and/or
-  :prop_tgt:`AUTOMOC_PATH_PREFIX` target property.
