Yes, I did have a flag that allows a package to say "I support
out-of-tree build". It defaulted to "NO" in generic-package, and to
"YES" in autotools-package and cmake-package, but can be overridden by
individual packages. For example, 'linux' can support out of tree build
even though it's a generic-package (well, now a kconfig-package), or an
autotools package may not support out of tree due to stupidities done
by the upstream developer.
However, this branch is now very old, and was far from being ready.
I really would like to put the smallest amount of work on Gwenhael
shoulders: I don't want to ask him, as a prerequisite of getting
gnuradio merged, to do some major surgery work deep in our package
infrastructure. So can we settle on a temporary solution that works for
gnuradio and is acceptable, and implement the grand plan of doing full
out of tree build at some later point?
