In this section we introduce step by step the installation procedure of CasADi. First we detail what software packages need to
be installed in order to use CasADi.
\section section2_1 Software requirements
CasADi consists of a symbolic core, which is strongly used by the interfaces that are shipped with it. Now we summarize
what the dependencies of each are. As a general rule you will always need a C++ compiler (tested with gcc 4.4.3) and
CMake (tested with version 2.8.2).

\section section2_2 Compilation
First, you have to get CasADi from http://www.casadi.org/ or check out the git repository from GitHub.
\code
$ git clone https://github.com/casadi/casadi.git -b tested casadi
\endcode
Set the environment variable <tt>CMAKE_PREFIX_PATH</tt> to inform CMake where the dependecies are located.
For example if Sundials headers and libraries are installed under <tt>\$HOME/local/</tt>, then type
\code
export CMAKE_PREFIX_PATH=$HOME/local/
\endcode
Go to directory of the source tree, create a directory called e.g. <tt>./build</tt> where all compilation-related files will be created.
\code
cd casadi; mkdir build; cd build
\endcode
Generate the <tt>Makefile</tt> by typing
\code
cmake ..
\endcode
Check the output of CMake if the dependencies are correctly located. The interfaces without underlying libraries and headers won't be compiled.
Adjust CMake variables (e.g. CMAKE_INSTALL_PREFIX if you want to install headers and libraries) by typing
\code
ccmake ..
\endcode
Now compile the C++ libraries.
\code
make
\endcode
And install headers and libraries
\code
make install
\endcode
If you wish to use the python interface you can compile it with the <tt>python</tt> target.
\code
make python
\endcode
