Strange, looks like you have libdw-dev 32bits installed? can you check
that? I.e. that cmake is not mixing somehow libraries?

Also I'm adding dwarves@xxxxxxxxxxxxxxx to the CC list, you don't have to
subscribe, but it would be a good idea, there are more people there that
I know have built this code on ubuntu/debian and that could be of more
help than me, that use debian rarely :-\
