[OpenCV]LAPACK in Version2.0

opencv 2.0裏面的變化還很多，採用lapack數學庫應該是一個巨大的進步。LAPACK (Linear Algebra PACKage) 是Oak Ridge 國家實驗室、加州大學Davis 分校和Illinois 大學等聯合開發的線性代數函數庫，用fortan語言編寫，有f2c的c接口，用於在不一樣高性能計算環境上高效求解數值線性代數問題。使用lapack應該能大大提升OpenCV的算法效率。這其實也是MATLAB曾經走過的路。

CXCORE now uses Lapack (CLapack 3.1.1.1 in OpenCV 2.0) in its various linear algebra functions
      (such as solve, invert, SVD, determinant, eigen etc.) and the corresponding old-style functions
      (cvSolve, cvInvert etc.)
