Yeah, at the moment it was a trade off between upgrading cmake or 
letting the older version of cmake dictate my source tree layout or 
learning another way to fake cmake into doing what I need.

I feel that I am spending more time on cmake than on the code at the 
moment, so I probably will not make any changes now in that direction, 
but might revisit it in the future if I need to refactor the cmake 
stuff. There are a lot of moving pieces at this stage, and I need some 
to be nailed down, even if temporarily so the work does not flounder.

I'm not that fond of it either, but it is what the project has been 
using. I suppose I could drop it all together, but that might be a 
bigger issue for some people than having to upgrade to the latest version.

This is still early stages in the project.
