That naturally will fix the problem (i have not yet really tried) but it still 
leaves the initial problem about cmake. It is very poorly designed in regards 
to multiarch systems. I hope they someday fix that. I btw. really wonder how 
systems with 32bit stuff in lib32 work out with cmake when trying to do 32bit 
development. I have not yet found anything in the documentation how it 
supports that.

Apart from this here.
