Qwt 6.1.6 make error , sqvrenderer

Hello all,

I am new to Qt and Qwt. I am working on a Debian 10. I want to use Qt and Qwt for an open source project. I ultimately want to use the plotting from Qwt in Qt Creator. I am using Qt 5.11.3
I have downloaded Qwt from sourceforge. I am using Qwt 6.1.6. I followed the instructions on this web page:
https://qwt.sourceforge.io/qwtinstal...wtinstall-unix

This is my error:

Code:

~/Downloads/qwt-6.1.6$ /usr/lib/qt5/bin/qmake qwt.pro

I thus get an error at qsvgrenderer. However, I don't know how to resolve this.
