[autoconf] added and updated some libs

I updated the conf file for 
* OpenCV, now it should work fine from version 2.3 to the actual version (2.4.5.)

I added two more libs
* lmfit, a C/C++ library for Levenberg-Marquardt least-squares minimization and curve fitting (http://joachimwuttke.de/lmfit/)
* GLM, an Alias Wavefront OBJ file library (http://devernay.free.fr/hacks/glm/)
