It's not the generating, it's recompiling all those files.  The cmake
build (and builder.py now, sort of) keeps track of dependencies, so
they only recompile files that have actually changed.  So it's the
difference between 30 seconds to recompile all the auto stuff that has
just had mtime updated (but identical content) and 3 seconds to
recompile the two files that actually changed and relink libpetsc.so.
