Building Shared Library with Project Builder

I want to release an SDK for my Carbon PEF application Isadora®.
Currently, I am building traditional carbon shared libraries (type =
shlb) with CodeWarrior, but I want to create a Project Builder version
so that people can build plugins in that environment.

Is there a way to build shared libraries with Project Builder? Or,
because it generates Mach-O code only, is this impossible.

If I can't build shared libraries, is the solution to get my app to load
Mach-O frameworks with CFLoadBundle?

Thanks in advance for the advice...

Best,
Mark
