Hi,
I am getting the following error while running make-
....

Does anyone know how to resolve it?
Thanks in advance

I just change the QOpenGLWidget into QGLWidget and passed. This link shows the answer.
https://askubuntu.com/questions/934836/fatal-error-qtwidgets-qopenglwidget-no-such-file-or-directory
But after that more errors occurred. Plenty of grammar problems of c++

Try to install and use prior version, such as http://www.libqglviewer.com/src/libQGLViewer-2.6.3.tar.gz

Also that README.md is better https://github.com/greatwallet/fastfusion
I made it works with Ubuntu 20.04
