Answer 1

You most likely don't have the developer pack for the OpenGL library. Install the mesa-common-dev package.

sudo apt-get install mesa-common-dev
sudo apt-get install freeglut3-dev

PS Such advice is useful for any library when something is not linked.

Answer 2

most likely, Qt cannot find the OpenGL library (I don’t know why it needs it to compile a freshly created pristine project in my case)
, first you can see what the symlink refers to:

forcibly link any of the found files in the format

sudo ln -s -f /usr/lib/x86_64-linux-gnu/mesa/libGL.so.1
 /usr/lib/libGL.so

PS: the advice may not be so good, but it was this sequence of actions that helped me in solving a similar problem

Answer 3

I found a solution to this problem on Stack Overflow:
sudo apt install libgl1-mesa-dev
