Subject: [PATCH] taskswitcher: Fix build when KWin is built without activities
 support
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fixes:
../kwin/mobiletaskswitcher/plugin/taskfiltermodel.cpp:81:40: error: ‘class KWin::Workspace’ has no member named ‘activities’; did you mean ‘ActivityRaise’?
   81 |     auto activity = Workspace::self()->activities()->current();
      |                                        ^~~~~~~~~~
      |                                        ActivityRaise

This occurs when KWin is built with -DKWIN_BUILD_ACTIVITIES=OFF:
