QMakeLibraryInfo uses external data to produce paths. This causes issues when trying to use it out of the existing qmake environment. Add data fields that contain the path to the binary that uses QMakeLibraryInfo and manually specified qtconf. Task-number: QTBUG-75870 Change-Id: Ic6fa274ede3a9287826ff66c79f155b10d0d455c Reviewed-by: Joerg Bornemann <joerg.bornemann@qt.io>
