5.9.1. Stuff to Remember When Creating this Section
This is a note from Alexander Kanavin regarding qt4 stuff.
Note
Qt4 recipes and classes have been removed in YP 2.1 because
Qt4.x has reached end of life upstream. For legacy applications
and LSB compliancy purposes Qt4 can be found in meta-qt4
repository, and for any new development Qt5 is available at
meta-qt5 repository(provide links to both).
