CMake is a cross-platform, open-source system for managing and automating the build process of software using a compiler-independent method.

When writing a CMakeLists.txt file make sure to NOT put any spaces in your projectname. Everything after the first space is interpreted as language to e enabled for the project ([[http://www.cmake.org/cmake/help/cmake-2-8-docs.html#command:project|see doc]] for details).

Right:
<code cmake>
PROJECT(WorldDomination)
</code>

WRONG
<code cmake>
PROJECT(World Domination)
