<![CDATA[Unable to build QT:Mqtt module]]>I have cloned the the source via git://code.qt.io/qt/qtmqtt.git.

I'm using Qt Creator 4.12.0
Based on Qt 5.14.2 (MSVC 2017, 32 bit)
Kits
0a79055f-c3c2-4f65-a189-ea66918d025a-image.png

This is the error

e0416c4f-d318-4e65-8bc7-47d4290ffda9-image.png

This is in the general messages

Project ERROR: Unknown module(s) in QT: mqtt
Project MESSAGE: perl -w C:\Qt\5.14.2\msvc2017_64\bin\syncqt.pl -module QtMqtt -version 5.15.0 -outdir "C:/New folder (3)/build-qtmqtt-Desktop_Qt_5_14_2_MSVC2017_64bit-Debug" -builddir "C:/New folder (3)/build-qtmqtt-Desktop_Qt_5_14_2_MSVC2017_64bit-Debug" C:/New folder (3)/qtmqtt

Has anyone experienced this issue? Thank you in advance.
