Hello and welcome.

-lGL is an option passed to the linker to link with the GL library. You do not have that, or it cannot be found.

You could Google for cannot find lGL and look through the causes/suggestions for whichever platform you have.

Hi and welcome to devnet,

This question has been answered numerous times over the years on this forum. You are missing the OpenGL development package from your distribution.

When searching for that error, either drop the dash or put "-lGL" in doubles quotes otherwise search engines will interpret it as "do not want lGL in the search results".
