We'll merge it to the 2.4 branch for the 2.4.3 release.  You can just 
test if from the CVS version because currently there has been no new 
development that won't be put on 2.4.

It is now in CVS and it will be in 2.4.3, and if CMAKE_PATCH_VERSION is 
not set you can assume an earlier version.

If you set the target property for the new feature but the CMake version 
is 2.4.2 nothing will happen because it ignores unknown properties.
