This package enable the use of the optimization alogorithm library \\href{http://ab-initio.mit.edu/wiki/index.php/NLopt}{NLopt}.
Since there are no packaging for the common operating system by default \\akantu compiles it as a third-party project. This behavior can be modified with the option \\code{AKANTU\\_USE\\_THIRD\\_PARTY\\_NLOPT}.
If the automated download fails please download \\href{http://ab-initio.mit.edu/nlopt/nlopt-${NLOPT_VERSION}.tar.gz}{nlopt-${NLOPT_VERSION}.tar.gz} and place it in \\shellcode{<akantu source>/third-party} download.
