I just type scons and this error message shows:

scons: Reading SConscript files ...

Package opengl was not found in the pkg-config search path.
Perhaps you should add the directory containing `opengl.pc'
to the PKG_CONFIG_PATH environment variable
Package 'opengl', required by 'glu', not found

Any ideas how to fix it?

DESCRIPTION="Linux Mint 21 Vanessa"

Fixed it using apt install libglvnd-dev. Should this be part of "How to build" @TTimo?
