support building all packages in the workspace including all dependencies

[mmerickel]

I have a workspace like src/*. Now I want to package a subset of those packages and install it into a new virtualenv somewhere.

Backstory example with pip

With pip-tools and uv pip compile I'm starting from a file that looks like this as requirements.in:

-e src/foo
-e src/bar
# ...

And I have a lock file requirements.txt containing:

-e src/foo
-e src/bar
pyramid==1.10.2
# ... all the other remote dependencies

My goal is to end up with a wheel folder containing wheels for foo and bar, as well as everything they depend on. I do it like this:

$ pip wheel -w wheels --find-links wheels -r requirements.txt

Later I can make my new virtualenv and install what I want (let's say just foo) from that wheelhouse via:

$ python -m venv some-env
$ some-env/bin/pip install -w wheels --find-links wheels foo

Adapted version with uv

$ uv export > requirements.txt
$ pip wheel -w wheels --find-links wheels -r requirements.txt

Now I've lost uv's excellent building features and I'm using pip directly instead.

Ideally I'd be able to just say "build wheels including all dependencies", and then I'd say:

$ uv build --wheel -o wheels --with-deps

And it would build foo and everything it depends on including bar, and any external dependencies. And it would use the uv.lock plus the current platform to determine what to build.

I see now this is a duplicate of #1681 which hilariously I even commented on in April so closing this, but maybe the examples are helpful to someone.
