[Cmake] Multiple PROJECTS with dependencies

[Dekeyser, Kris]

I agree that that would be handy, but if so, I would prefer to have that
optional.

Our build tree consists of a very large number of projects (one system
consists of 911 projects !!). This is only manageable because we organize
them in 2 directory levels (Workspaces and SubSystems). Of course the number
of dependency projects (direct and indirect) can be very large as well. We
would certainly need to be able to access workspaces with only a single
project or all the projects in a certain sub-system.
