[CMake] How to set Overwrite or no over write in install(FILES ....)?

[Petr Kmoch]

Hi Jupiter,

regarding your second question: you'd need to escape the nested
quotes. Also, I'm not sure if 'not exists' can be given in lowercase.

However, I'd strongly suggest using install(SCRIPT ...) instead of
install(CODE ...), precisely because of the escaping issues.
