That's part of what attracted me...

If you want to do that separately, I'll try to fix it.

meson does depend on ninja (to execute the build) and of course python. But
the rest should be optional dependencies. ninja builds without any
dependencies as long as you don't change its parser sources. python builds on
aix, hpux etc.

Not sure what way gdbm openssl(at)1(dot)1 and sqlite are pulled in? I assume readline
is for python...

Yes, that shouldn't be a problem. You can run arbitrary code in targets
(there's plenty need for that already in what I have so far).
