I'm not sure file(COPY) implements the same copy-if-different semantics 
as configure_file (or creates dependencies to re-run CMake when an input 
changes). You might want to use configure_file(COPYONLY) instead.

Note there is also an @ONLY if you do need to perform substitutions but 
need to leave ${} alone.
