This might be a problem. I'm running cmake version 2.8.10.2 and I might 
need to up the minimum version to 2.8.10 as I think that is the version 
that allows you to build obj files in a tree and then assembly them into 
a single library, which is what I'm doing.

My cmake files were not designed to work outside the source tree. I 
think all your errors above are a result of this. I didn't think about 
doing this, but there is no reason that I could support this at some 
point. I'm very new to working with cmake so suggestions, help and/or 
pull requests would be appreciated. I suspect that I would need to 
establish the root of the src tree, then make all the paths absolute or 
something along those lines. Do you have an example of a project that 
does this?

I just pushed a minor fix to add -fPIC so the libraries will link now on 
linux. 825b40e..209c592  sew-devel-2_0 -> sew-devel-2_0

Thank you for taking the time to test this and report back.
