This package enables the use the \\href{http://www.labri.fr/perso/pelegrin/scotch/}{Scotch} library in
order to perform a graph partitioning leading to the domain
decomposition used within \\akantu
Under Ubuntu (14.04 LTS) the installation can be performed using the commands:
\\begin{command}
> sudo apt-get install libscotch-dev
\\end{command}
If you activate the advanced option AKANTU\\_USE\\_THIRD\\_PARTY\\_SCOTCH the make system of akantu can automatically compile Scotch.
If the automated download fails due to a SSL access not supported by your version of CMake please download the file \\href{https://gforge.inria.fr/frs/download.php/28978/scotch\\_${SCOTCH_VERSION}\\_esmumps.tar.gz}{scotch\\_${SCOTCH_VERSION}\\_esmumps.tar.gz} and then place it in the directory \\shellcode{<akantu source>/third-party}
