[QBS] How to check minimal supported Qt version?

[dismine]

Thanks you, i think i have found good example.

import qbs
import QbsFunctions

Product {
    Depends { name: "Qt.core" }
    property string minimumQtVersion: "5.1.0"
    condition: QbsFunctions.versionIsAtLeast(Qt.core.version,
minimumQtVersion)
}
