What I mean by avoid: the rest of submodules we would need to replace in
place (which I mean by devendor). I have tried to add a build
phase doing so, but wasn't successful by now. It will be a
huge amount of work added anyways, which would take me a bigger amount
of time.
For some reason disabling the bundled version of boost still seems to
leave some links to the bundled boost in the build, so when I remove it,
the build fails.

I don't see use to discuss this as I would like to get to get this done
and I don't need it.
v3 coming soon, I hope i get the changelog right this time...
Cheers.
