Hi Raphael,

this one broke the polly build, because the libraries we are linking 
(libisl and libcloog) are not anymore in the rpath (and they are also 
not in the LD_LIBRARY_PATH). Is this change intended? Do you have an 
idea how to proceed? Is this a problem with your change, should I fix 
the Polly cmake or should we now always put such libraries into the 
LD_LIBRARY_PATH? (changing the buildbots may take a little).

Unfortunately I am about to head to bed, so I can not really investigate 
this right now.

Thanks,
Tobias
