Ok, so you're ignoring boost users who don't fit the same mold as you. You
should make this more explicit in your plan. (I also think you should expand
your mind a bit).

Oh, you don't understand.

And where would the cmake files come from? How would they appear in the
packages? They have to be generated, remember. Are you going to make cmake a
hard requirement just to generate some files?

I think you need a much more specific plan. I think you don't understand the
problem yet.

I think you need to expand your mind beyond 'the user downloads the source
and builds it'. You are missing entire worlds.

And hitting conclusions like this is where you will hit community friction
eventually I'm sure.

I don't know what you mean here. My suggestion improves the experience 'in a
short time frame'.

Anyway, you have made clear that only 'people building top of tree from
source as part of building their own stuff' is the scope of what you're
interested in. You have also made clear that you don't know what cmake
packages are, and you have said you never use them. You don't seem to want
to look outside your own bubble.

Given those points it's clear to me that you didn't understand my mailing list post.
