Support cabal new-build

[ivanperez-keera]

Apparently, something needs to change to support this.

PR #62 Needs to be split in two, one for this issue and one for issue #61 .

It seems that some people do not include the cabal.project file in the repo. instead, they ignore it:

See https://github.com/haskell-hvr/uuid/blob/6591726483cbef136c836d32445807a63b1ff265/.gitignore

Any thoughts?

cabal.project.local and cabal.project are different. They do include the cabal.project, but not cabal.project.local. cabal new-configure will create cabal.project.local, its purpose is:

• When you depend on a library that's not part of the same project, is available on a local filesystem, and won't necessarily be in the same absolute or relative location on every developer's machine.
• When you want to locally override an existing dependency to specify a WIP version of that dependency either on the local filesystem or in a VCS
