This project requires two APIs: Qt and Qwt.
Qt is an opensource API for GUI development in C++ and QML. You can donload the installer at the following location: https://www.qt.io/download-open-source/?hsCtaTracking=f977210e-de67-475f-a32b-65cec207fd03%7Cd62710cd-e1db-46aa-8d4d-2f1c1ffdacea
QWT is a legacy graph and plot plugin for Qt. Qt comes with its
own Qt Charts, but is proprietary and requires an additional license.
Instead, we use QWT.
