OK, so "-P" means that cmake won't produce a new Makefile.

But don't I *need* to create a new Makefile?  I thought the goal was
to produce a new Makefile whose "install" target has been affected by
the "-DCMAKE_INSTALL_COMPONENT=Headers" argument.

If "-P" prevents the creation of a new Makefile, it sounds like we're
discarding the very Makefile that we're trying to create.

Would you mind clarifying?

Thanks,
