https://info.qt.io/download-qt-for-application-development
In the website of Qt, download the Qt installer open-source application development. Then go to the directory where it is downloaded, make it executable and run it as root:
chmod 777 qt-unified-linux-x64-3.0.0-online.run sudo ./qt-unified-linux-x64-3.0.0-online.run
When the next window appears then click on skip to continue without registering.
Then choose the installation path, the default one is usually a good choice.
sudo ln -sf /opt/Qt/Tools/QtCreator/bin/qtcreator.sh /usr/local/bin/qtcreator
