I think that was the wrong track, i should ignore all these "Qt4" qmake things.
This "Add Library" is to add a dependency, and at this stage, i can
manage that manually.
I just want helpers that would create qbs skeleton code for a
"composite" project.
I wrote a "Qbs Subdir Project" custom wizard, I now just need to be
able to chain that.

AFAIU, it should be managed in the ProjectExplorer::ProjectNode implementation.

It is hooked up on the context menu "New Subproject...". "Add new..."
is already supported by qbs project manager, ...

The difficulty is to add support for editing the "references" property
of a Project item:

I quickly hacked the QtCreator side (easiest part), and added stubs to
the Qbs API. the "New subproject..." is now enabled and gives me the
"New project" wizard, it seems that the list of available "Custom
Wizard" based items is filtered by "supported build system", this is
pretty cool so far. I can even see my custom "Qbs Subdir Project"

Christian, any thoughts on adding this capability to Qbs core API? How
hard is it to handle adding/removing references?
Given https://github.com/qbs/qbs/blob/master/src/lib/corelib/api/project.cpp#L496,
this doesn't look trivial to me, but shouldn't be that hard for
someone who knows the internals very well... ;)


Attached are a diff for Qtc that just enable the feature and forward
stuff to Qbs API and another one for Qbs that just add stubs.
