I guess I have two concerns.

1. Windows is not good with lots of files/dirs (can be slow)

2. Naming and tracking these dirs maybe difficult giving the current api 
to try-compile/try-run.

If someone wants to try and implement this, it would most likely be a 
good thing if it can be done.  It would require lots of testing with big 
existing cmake builds like KDE,ParaView, ITK.

That said given the current API, you could have a project that does this 
in the cmake language today.  You just could not use some of the 
standard macros.
