Given how difficult it is for me to get someone with approval
privileges to even comment on the patch that allows someone to
build with zlib at a non-standard location, I would say that
this is not the friendliest option at the moment.
I know the patch I proposed is not perfect, but I believe it is
the most pragmatic under the circumstances. I would also accept
and understand a reviewer's rejection of my patch; but since
the alternatives are going to be a significant amount of work
for reasons I do not believe are sufficiently important, I will
pass on that.
