orzel,

Thanks for the patch...

I'm not fully agree to remove clapack code from digiKam core, because i want to
limit external depencies for digiKam, especially under windows, where it's not
easy to compile whole digiKam & co

But there is an advantage to use Eigen lib, if code use processors
optimizations to speed-up code.

This is my proposal : set Eigen depency as optional. If it found, we compile
digiKam core with it, else, internal Clapack code is used. I do the same with
liblqr currently.

What do you think about ?
