I've just replaced this change with a more general solution.  Instead of 
doing

SET(CMAKE_HIDE_TARGET_DIRS 1)

you can instead do

SET(CMAKE_TARGET_DIR_PREFIX ".")

This approach has several advantages:

1.) It is useful on Windows to set a prefix that will at least group all 
the directories together since they cannot be hidden by changing the name.

2.) It still allows the directories to be hidden on UNIX.

3.) The prefix can have a slash in it so it can be used to group all 
target directories under a single directory (per source directory):

SET(CMAKE_TARGET_DIR_PREFIX ".cmakedirs/")
