Cake core folder

I have put together an nGinx server and on my shared host I just created a "lib" folder outside of root and modified the webroot/index.php file to point to the Cake folder location.

 

How are other people setting this up on their end using nGinx I am wondering? Does it make any difference where?

 

usr/lib/share

usr/lib

usr/src

 

Thanks,
