I do not follow this. Are you saying something is going to parse the code 
and setup the links? During which build?

There is no soft links on Windows. Actually I think if would use hardlinks 
to directories the issue would be resolved automatically.

What if I have local changes, but want to update to HEAD on master branch of 
other libs? I think this is very common need and we should document steps 
one needs to take for this.

I was running on freshly cloned tree. What else does it needs to clone?

Do we have a test on demand? In any case I might want to do a local test

Can we setup some kind of scripts to help developers with routine tasks like 
this? I probably do not want to keep 2 trees around, but rather switch back 
and forth when necessary.
