This what the log looks like:

When trying to install libglu-dev I get the following message:

Note, selecting 'libglu1-mesa-dev' instead of 'libglu-dev'
libglu1-mesa-dev is already the newest version.

I get this error when installing G20. I understand that this means the linker is missing the option -lGLU.

My question is how do add this to the linker in the CMakeLists.txt file
