Obtaining and installing cmake per se

DIET requires using cmake at least version 2.4.3. For many popular distributions cmake is incorporated by default or at least apt-get (or whatever your distro package installer might be) is cmake aware. Still, in case you need to install an up-to-date version cmake's official site distributes many binary versions (alas packaged as tarballs) which are made available at http://www.cmake.org/HTML/Download.html. Optionally, you can download the sources and recompile them: this simple process (./bootstrap; make; make install) is described at http://www.cmake.org/HTML/Install.html.
