This introduces a new variable, QT_VERSION_INT, which allows
qmake files to more easily do Qt version checks.
Previosly, code would chain greaterThan/equals/lessThan with
logical ands for QT_MAJOR_VERSION and QT_MINOR_VERSION.
That worked OK, but was a little verbose, and is inconvenient
if you want to use a QT_VERSION check alongside other conditions
in a conditional.
The QT_VERSION_INT is a string variable is of the form:
Qt 5.0.0: 50000
Qt 5.6.1: 50601
it is base 10, and can be used with qmake's comparison operators
like so:
greaterThan(QT_VERSION_INT, 50600) {
// Do stuff for Qt > 5.6
}
This commit also removes our own copies of QT_MAJOR_VERSION
and QT_MINOR_VERSION. These are provided by mkspecs/qconfig.pri,
and have been since (at least) Qt 4. So they're already available.
We don't need to provide them. Our method of fetching them was also
buggy due to Qt 4 compatibility - so that's fixed now.
