Otherwise we get warnings that some documentation items don't have corresponding #define, and more importantly the corresponding snippets are not included in the output. For that we need a modified version of the "full" argument for config.pl. Also, the new CMakeLists.txt target only works on Unix (which was already the case of the Makefile target). Hopefully this is not an issue as people are unlikely to need that target on Windows.
