nmake install
in the build folder if you are using Visual Studio andmingw32-make install
if you are using MinGW -
@SGaist After made make install I got the following:

And still after running the example again, the devices list is empty.

As the error suggests: you are missing Perl. Install it.
It’s normal noting changed, the module wasn’t even built.

@SGaist During installation process of QT this problem occurred:
So I clicked 'Ignore'.
Then I tried to install "C:\Qt\Qt5.10.0\Tools\Perl52213_32\strawberry-perl-5.22.1.3-32bit.msi
but nothing changed.
I tried to reinstall it and disabled Antivirus and the same error appeared.
Is there anyway to overcome this problem? -
Did it install successfully ?
If so did you try to call perl from a new command prompt ? -
@SGaist I restarted the Qt command line and the error that related to Perl disappeared and I got the following:

Thanks for your response!

You should also use the correct command line prompt for building especially if you start with the one provided by Visual Studio.
