Install QtMqtt - g++: error: unrecognized command line option '-Wdate-time'

[jbenfica]

I am trying to install the QtMqtt module in the already installed Qt 5.11.2. I have installed Perl 5.28 and Python 3.7.1. I use Windows 7.

I make the git clone in git clone git: //code.qt.io/qt/qtmqtt.git no problem

after:
qmake -> ok
make install or mingw32-make install, so much the same error appears as it is:

g ++: error: unrecognized command line option '-Wdate-time'

Can you help me??

Hi and welcome to devnet,
