 Some Linux distributions may have ready to install packages available for some of these, for other distros you may need to build these from code or search hard for binary installations. You may require your system managers help to set all these up properly.   Some Linux distributions may have ready to install packages available for some of these, for other distros you may need to build these from code or search hard for binary installations.

So, for example, when using the ''GNU'' compiler suite to build a ''debug'' version of the software, you'd have to create a build directory named ''gnu_debug''. Other options are ''gnu_opt'' for optimized build without debug symbols, or ''gnucxx11-opt'' if your system supports ''cxx11''.

 ===== Build Options ===== ===== Build Options =====
 Build options can be specified in two ways. The preferred, "static" way of doing this is through the different variants files. These settings can be overridden by the user, either by setting options on the command-line when invoking ''cmake'', or by edit them by using the semi-graphical environment ''ccmake''. Build options can be specified in two ways.

 +==== Packages ====
 +
 +To find external packages (like casacore, aoflagger, etc) one can add directory pointers to the CMake command line like these:<code>
 +-DCASACORE_ROOT_DIR=/opt/cep/casacore/current
 +-DAOFLAGGER_ROOT_DIR=/opt/cep/aoflagger/current
 +</code>
 +etc.
