Debian package does not enforce Qt version selection

[balbirthomas]

On Debian systems qmake is a link to qtchooser which selects between possible alternative versions of Qt that may be installed. Event though the debian/controls file lists the build time dependencies as Qt5 qtchooser may run a different version of qmake causing a build failure (as did happen on my Debian/Jessie - latest stable system without Qt4 installed). In order to fix this all that is required is an additional line (given below) in the debian/rules file

export QT_SELECT=5

Kindly consider adding this.
