REVISION SUMMARY
  autouic (like automoc) assumes that every ui_*.h include statement it finds
  relates to a .ui file that needs generating. this is not always true.
  
  e.g. we have software which generates ui_debug.h which is simply
  a qloggingcategory header for the UI category of that software which would
  then trip up autouic because it would assume there's a .ui file when there
  really isn't one.
  
  unfortunately the ui_ assumption cannot be selectively disabled, so we
  can't have explicit listing of .ui in source lists
  
    set(foo_SRCS foo.cpp foo.ui)
  
  without also getting the not particularly compatible include assumptions.
  this should be revisited for kf6 since there isn't a technical need for
  files to be called ui_*, they could just as well be *_ui or anything else
  so as to not clash with autouic assumption.
  
  autorcc does not suffer from this problem so we can leave it enabled, for
  now anyway.
