Our PPA has builds for all Ubuntu releases except for Saucy, this is because we are still waiting for a fix to land in Saucy (Ogre3D SRU) which should be any day now.
We are going full dynamic libs here, so our users will need to first have our build PPA then openmw PPA, this is the same as for any developer using our PPA. We are moving away now from static libs.
build libs:
ppa:openmw/build
releases:
ppa:openmw/openmw
We'll think about merging these into one eventually.
With time, this won't be necessary at all and we'll just push to Debian.
