CGAL安装向导
看了英文的介绍，感觉还是用中文记录下比较好，以后再看就快很多了。
CGAL安装向导
1，下载CAGL的文件后，需要使用CMake生成待编译文件：
cd CGAL-4.0.2 # go to CGAL directory
cmake . # configure CGAL
make # build the CGAL libraries
cd examples/Straight_skeleton_2 # go to an example directory
cmake -DCGAL_DIR=$HOME/CGAL-4.0.2 . # configure the examples
make # build the examples
这里需要安装CMake,2.6.2以上版本才可以；
2，当前最新版本4.0.2支持的环境
| compiler | operating system |
| Gnu g++ 3.4 or later 1 | Linux / MacOS X |
| MS Windows 95/98/2000/XP/NT4 | |
| Intel C++ 11.0 or later2 | Linux |
| MS Visual C++ 9.0, 10.0 (Visual Studio 2008 and 2010)3 | MS Windows 95/98/2000/XP/NT4/Vista/7 |
3 CMake
需要安装Cmake,2.6.2以上版本；
4第三方软件支持
4.1STL
4.2BOOSt的支持，
boost可以在这里下载http://www.boostpro.com/download/
4.3 Gmp和Mpfr库
Having Gmp version 4.2 or higher and Mpfr version 2.2.1 or higher installed is recommended. These libraries can be obtained from http://gmplib.org/ and http://www.mpfr.org/, respectively.
4.4core
是CGAL核心依赖的库之一，Core is a library that provides a number type for computing with real numbers; that is, it allows to represent expressions with square roots involved. This package is useful when dealing with curved objects.
4.5leda
不是必须的

4.6RS
RS (Real Solutions) is devoted to the study of the real roots of polynomial systems with a finite number of complex roots (including univariate polynomials).
In Cgal RS is used by one model of the Algebraic Kernel.
RS is freely distributable for non-commercial use. You can download it from http://vegas.loria.fr/rs/. The library RS needs Mpfi, which can be downloaded from http://mpfi.gforge.inria.fr/. Version 1.4 or higher is recommended.
4.7 OpenNL
OpenNL (Open Numerical Library) is a library used to easily construct and solve sparse linear systems.
In Cgal it is the default solver for the Surface Mesh Parameterization package.
The OpenNL's main Web page is http://alice.loria.fr/index.php/software/4-library/23-opennl.html. Cgal includes a version of OpenNL in C++ made especially for Cgal by Bruno Lévy.
必须要装，装了它，就可以不用blas,lapack,Taucs
4.8 Eigen
Eigen is a C++ template library for linear algebra. Eigen supports all matrix sizes, various matrix decomposition methods and sparse linear solvers.
In Cgal, Eigen provides sparse linear solvers in the Surface Reconstruction from Point Sets and the Planar Parameterization of Triangulated Surface Meshes packages. Since Cgal version 4.0, Eigen is recommended over Taucs that is not longer maintained.
In addition, Eigen also provides singular value decomposition for the Estimation of Local Differential Properties and the Approximation of Ridges and Umbilics packages.
The usage of Eigen allows to remove lapack, blas and Taucs from the list of third party libraries required by some Cgal packages. Note that the version 3.1 (or greater) of Eigen is required.
The Eigen web site is http://eigen.tuxfamily.org.
4.9 Taucs
Taucs is a library of sparse linear solvers.
In Cgal, Taucs can be used by the Surface Reconstruction from Point Sets package, and by the Planar Parameterization of Triangulated Surface Meshes package. Note that since Cgal 4.0, Eigen is recommended over Taucs.
The Taucs website is http://www.tau.ac.il/~stoledo/taucs/.
The latest official version is Taucs version 2.2, September 4, 2003. Copyright (c) 2001, 2002, 2003 by Sivan Toledo, Tel-Aviv University, [email protected]. All Rights Reserved.
See http://www.tau.ac.il/~stoledo/taucs/ for the license and the availability note.
Used by permission of Sivan Toledo.
The Cgal project provides a modified version of Taucs in the download section of http://www.cgal.org/. This version fixes some bugs, supports 64-bit platforms, and allows a simplified installation process. It also contains a complete lapack implementation.
As Visual C++ is not properly supported by the Taucs project, we provide a precompiled version of Taucs, which can be downloaded with the installer CGAL-4.0.2-Setup.exe.
CAUTION: Since version 3.3.1, Cgal is no longer compatible with the official release of Taucs (currently 2.2). Make sure to use the modified version provided in the download section.
有了Eigen可以不装，如果要装，最找装CGAL提供的版本，里面还含有lapack.
4.10 Blas
blas (Basic Linear Algebra Subprograms) is a library of basic vector and matrix operations.
In Cgal, blas can be used by the packages Estimation of Local Differential Properties and Approximation of Ridges and Umbilics only. Note that if Eigen is available on the system, blas is not required anymore.
You can download the official release from http://www.netlib.org/blas/. Alternatively, installing Taucs customized for Cgal provides blas.
装了Eigen，可以不装
4.11 Lapack
lapack provides routines for solving systems of simultaneous linear equations, least-squares solutions of linear systems of equations, eigenvalue problems, and singular value problems.
In Cgal, lapack can be used by the packages Estimation of Local Differential Properties and Approximation of Ridges and Umbilics only. Note that if Eigen is available on the system, lapack is not required anymore.
You can download the official release from http://www.netlib.org/lapack/. Alternatively, installing Taucs customized for Cgal provides lapack.
可以不装，在CGAL提供的taucs库的包含有
4.12 Qt
Qt is a cross-platform application and UI framework.
Most Cgal demos use Qt3 or Qt4. Having Qt4 version 4.3.0 or higher is recommended.
In case Qt is not yet installed on your system, you can download it from http://qt.nokia.com/.
跨平台编译环境，这个得装
4.13 libQGLViewer
一些三维的例子有用到
4.14 Coin
Coin is an implementation of Open Inventor.
In Cgal, Coin is used in the demo of the Kinetic Data Structures package.
You can download it from http://www.coin3d.org/. 可以先不装
4.15 zlib
zlib is a data compression library.
In Cgal this library is used in the examples of the Surface Mesh Generation package.
If it is not already on your system, e.g., on Windows, you can download it from http://www.zlib.net/.

4.16 ESTBL
The Esbtl (Easy Structural Biology Template Library) is a library that allows the handling of Pdb data.
In Cgal the Esbtl is used in an example of the 3D Skin Surface Meshing package.
It can be downloaded from http://esbtl.sourceforge.net/.
