I suspect you'll need to pick apart ./configure_uw and aggressively disable cmake flags.  For example, the error you reference on 16.04 is due to a failure building a unit test.  You can do without those!

All variants of the compilation should result in a compatible protocol layer.  However, if you disable some of the security libraries (think Globus, Kerberos), the security negotiation might fail.
