[eigen] Embedding Eigen in a software

[Ronan Trépos <Ronan.Trepos@xxxxxxxxxxxxxxxx>]

Dear Eigen community,

I took a look to this library in order to use it in a modelisation 
plateform tool
(VLE plateform, in french : 
http://vle.toulouse.inra.fr/mediawiki/index.php/Accueil).
And I have  some questions.

A great number of our users are working on Windows plateform.
So a windows installer is required. I saw that CMake was used to install 
the eigen library and I was wondering if a
FindEigen file was developped in order to link any CMake application to 
Eigen. And more generally, does a
a "classical" process exist to embed Eigen into softwares ? Did you 
already have any other experiences of this kind ?

In a first attempt to use linear algebra algorithms in VLE plateform, we 
relied on boost ublas library (without LAPACK bindings).
This was technically convenient since the platform is already linked to 
boost. Nevertheless, it seems that
solvers like e.g. eigenvalues  problem, cholesky or QR decomposition are 
not part of the release and can be found (sometimes)
in cpp examples on the Web. And since I do not have a lot of skills in 
linear algebra, I prefer not implement these algorithms myself.
This is the reason of my interest for Eigen.

Any advice and answer would be greatly appreciated.

In advance, thank you
R. Trépos
