CMP0003 does not require that you use full paths.  If you set the policy 
to NEW, and your stuff works (i.e. it builds and links), you are all 
set.  You should not get any warnings, and things should be fine.  So, 
no need to leverage for the NEW style, just use it.  There are very rare 
cases where the NEW style will break something, and they are very easy 
to fix (just add an extra link_directories call).
