A little off topic, but GCC via gcc_xml 
http://www.gccxml.org/HTML/Index.html is built by CMake, and did not 
require a language.  Most of the complication comes at build time with 
custom commands that generate files that generate files, that generate 
files.   The build script it self does not have to do much programming. 
  Most of the hard work is pushed to build time, and not CMake time.
