I don't see anything to say either way - and I'm not very familiar with 
cmake.
grepping build dir for cblas finds:

With %cmake -DCMAKE_VERBOSE_MAKEFILE=ON I get the following which may be 
of use, but I can't see it, unless it's to do with the --no-as-needed
which seems to be reversed later. This is probably done by our %cmake macro.
