[CMake] Make project name a target

[Marcel Loose]

Hi David,

I don't see the exact difference between (1) and (2). And yes, I was
thinking of using the project name as a target. You are right, that it
might cause clashes with existing projects, though :-(

We use the convention that project names are always capitalized, so we
usually don't run into problems.

Is there a nifty trick to wrap the 'project' command? I never succeeded
in doing that.

Best regards,
Marcel Loose.
