I do not mean to be rude, but please scrap it. Or make Lua the only  
language allowed in CMake. But having two languages is going to be bad  
because in the end, we will need to know and at least be able to  
understand two languages as there will be CMakeLists.txt,  
FindXXXX.cmake, etc files in both languages.

Before Lua is added as a language to CMake, I'd like to ask a  
question: is there really a need for Lua (or any other language) or is  
the current CMake scripting Turing-complete and able to do anything  
which could be done with Lua?

Please note I'm not against Lua but only against having to know two languages.

Thank you.
