Qt 6: cannot find -lOpenGL

[fem_dev]

I have a Qt C++ application that compiles Ok with Qt 5.15.0, but, when I switch to Qt 6.0.0 I got this compile time error:

cannot find -lOpenGL

So, I tried to install again this package:

sudo apt-get install build-essential libgl1-mesa-dev

And use locate to show the installed files:

locate libOpenGL
/snap/gnome-3-34-1804/36/usr/lib/x86_64-linux-gnu/libOpenGL.so
/snap/gnome-3-34-1804/36/usr/lib/x86_64-linux-gnu/libOpenGL.so.0
/snap/gnome-3-34-1804/36/usr/lib/x86_64-linux-gnu/libOpenGL.so.0.0.0
/snap/gnome-3-34-1804/60/usr/lib/x86_64-linux-gnu/libOpenGL.so
/snap/gnome-3-34-1804/60/usr/lib/x86_64-linux-gnu/libOpenGL.so.0
/snap/gnome-3-34-1804/60/usr/lib/x86_64-linux-gnu/libOpenGL.so.0.0.0
/snap/kde-frameworks-5-core18/32/usr/lib/x86_64-linux-gnu/libOpenGL.so
/snap/kde-frameworks-5-core18/32/usr/lib/x86_64-linux-gnu/libOpenGL.so.0
/snap/kde-frameworks-5-core18/32/usr/lib/x86_64-linux-gnu/libOpenGL.so.0.0.0

But I got the same error again....

What is wrong with Qt 6 setup?

My system:

• Ubuntu 20.04 x64
• Qt Creator IDE 4.14.0

@booter Do you have a question?
If you get this error - did you install the packages mentioned in this thread?
