Как добавить QT qmake версия 4.8 спокойному создателю?

У меня есть спокойный создатель 5.4.1. У меня есть qmake 5.4.1, но я бледный для добавления qmake 4.8 для настольной версии. Как я мог сделать?
Я устанавливаю gcc4.8, но я не знаю, установка qmake? (если это установило поэтому, где это было?)

root@ubuntu:/home/hgh1# sudo apt-get install gcc-4.8
