As with other programming languange, Lua can add functionality by using require statement. Path to search for modules defined by package.path and package.cpath settings.
package.path : Where Lua looks for .lua modules.
package.cpath : Where Lua looks for .so/.dll modules.
We can append the path like :
package.path = package.path..”;/home/user/lib/?.lua”
package.cpath = package.cpath..”;/home/user/lib/?.so”
