[chiusa] errore librerie

Salve, sto cercando di installare ktechlab il quale richiede librerie qt5 e altro. seguendo un altra guida in rete mi sono trovato a risolvere parzialmente il problema con cmakegui questa guida. Ora all'ennesimo tentativo di dare il comando cmake .. dà un elenco lunghissimo di errori e file mancanti. consigli?

Installing in /usr/local. Run /home/qobu/Scaricati/ktechlab-master/build/prefix.sh to set the environment for ktechlab.
