I copied all qt4-files from 7.X repo manually into the optional-folder of my 8.1.5 tc and made some really ugly and dirty adoptions (renamings) in the .dep files. Now I can run qmake and make and it fails at the beginning, because it cannot find some headers, but those files are at least somewhere . Does anyone have an idea?
/usr/local/bin/qmake -o Makefile GUI.pro
