How do you build a cube project?

[ambalboa]

A solution I am building includes a cube project, that I am able to build seperately in VS 2005, but not in VBP.

I've placed numerous files with the extension *.dwproj, *.dwproj.user, and *.cube in the filename field, and I get an "Unsupported project type" error every time.

How can I build this project?
