Yeah something is going to have to get fixed there. I don't understand why
they want to use @rpath which requires Mac OS X 10.5 or greater. I'd like
to rip that out and replace it with plain old absolute-path install_names
which we use almost everywhere in MacPorts and they work great on all macOS
versions.


Before putting any effort in that direction, I suspect ninja might not even
work on ppc (or at least I don't find it on package server), so you might
be serving i386 10.4 only, a super rare species. Another issue is that it's
nontrivial to make tests work before binaries are installed.

I would support the idea of supporting both options, but we need to get at
least one working first.

MacPorts doesn't have an option called "build_dir" so I don't even know how
this is working...

Why do we need an additional level of indirection? Why can't we just:

default build.dir           {${workpath}/build}
default configure.post_args {"${configure.dir} ${build.dir}"}


I started copying cmake setup. Feel free to fix it (I'm not behind my
computer).
