macro NDEBUG is defined in debug mode

macro NDEBUG is defined even in debug mode, apparently part of the Qt_DEFINES_ variable.

Also, the development version downloaded from https://download.qt.io/development_releases/vsaddin/2.4.3/ is broken, gives error:

Severity Code Description Project File Line Suppression StateSeverity Code Description Project File Line Suppression StateError MSB4086 A numeric comparison was attempted on "$(QtVersionMajor)" that evaluates to "" instead of a number, in condition "$(QtVersionMajor) > 5                  OR ($(QtVersionMajor) == 5 AND ($(QtVersionMinor) > 13                    OR ($(QtVersionMinor) == 13 AND ($(QtVersionPatch) >= 2))))". kiwi_client C:\Users\lih\AppData\Local\QtMsBuild\qt_vars.targets 145
