Hi Dave:

I was surprised you didn't take the conservative course here since
that is the CMake tradition for dealing with regressions, and the find
modules for lapack/blas are dealing with a particularly complicated
lapack/blas ecosystem where it is easy for these find modules to go wrong
for some platforms.  However, I also recognize that this is your
judgement call to make, and I do hope that you are correct that the
benefit of these post-2.8.5 changes is really worth the cost of the
lapack/blas library inconsistency regression that was introduced by
the changes.

I will try to come up with a fix for the regression early in the next
release cycle and run it by the lapack/blas find module maintainer,
Alexey Ozeritsky.
