yes, I have that problem too. I guess you read the config class with NoGL
and the discussions in the VM

I didn't have this one.

Yes, maybe. But what do you gain?  there is 1 minute of difference between
the build (the cmake .) and the make. Sooner or later something will fail
and you will need to install the dependencies.
For me, what it would be better is to DOCUMENT which are the needed
decencies/packages.
In fact, I would love to provide a script doing all necessary sudo apt-get
to get all you need (and the same for others distros than Debian/Ubuntu). In
Mac there is no problem because with the 4gb Xcode you have all the libs.
