Martijn Berger (Juicyfruit) has done a great job making an Alembic fork on github, to get rid of all the annoying cmake errors in Alembic sources.
https://github.com/martijnberger/alembic A pull request has been made to try and get these changes into Alembic. For the time being i would suggest using Martijn's version, which apart from build file fixes is the same as official Alembic.
