Document installation of custom plugins using CMake.

    Description

      The CMake manual does not cover the installation of custom QtDesigner plugins. FindQt4 used to supply the QT_PLUGINS_DIR variable, but there doesn't seem to exist a Qt5 equivalent. I ended up doing the following, which may be worth including in the manual:

      #Install the designer plugin
if(QT_PLUGINS_DIR)
  # Legacy FindQt4.
  install(TARGETS ${Library}
    RUNTIME DESTINATION "${QT_PLUGINS_DIR}/designer"
  )
else()
  # Call qmake to query the plugin installation directory.
  get_target_property(QT_QMAKE_EXECUTABLE Qt5::qmake LOCATION)
  execute_process(COMMAND ${QT_QMAKE_EXECUTABLE} -query QT_INSTALL_PLUGINS
    OUTPUT_VARIABLE QT_INSTALL_PLUGINS OUTPUT_STRIP_TRAILING_WHITESPACE
  )
  install(TARGETS ${Library}
    RUNTIME DESTINATION "${QT_INSTALL_PLUGINS}/designer"
  )
endif()

      Better yet, Qt's CMake files could reintroduce the QT_PLUGINS_DIR. Anyway, it should be documented.
