Yes.  This is a great cmake feature. Boost.CMake now uses this to 
install a $PREFIX/lib/Boost.cmake file.  So if you happen to know where 
your boost is, you can make use of it with the same code whether your 
tree is installed or not.  One thing I noticed:  if you link to 
boost_threads-mt-shared, for instance, with the installed exports you 
automagically get -pthread and friends, but with the noninstalled 
exports you don't.  Is this expected?
