There are many ports using the cmake portgroup that do this, using commands 
like the ones shown earlier in this thread. Some months ago I added to my to-do 
list, but did not begin to work on, a project to modify the cmake portgroup to 
always do an out-of-source build. This would involve removing from the existing 
ports any manual implementations of this, and testing all the ports using the 
portgroup to verify that they still build. Since out-of-source builds seem to 
be very common and recommended for cmake, I expect all ports to support this, 
but if not, an option could be added to the portgroup to let ports opt out.
