#include a standard library in a custom library

Thanks for your reply PaulS,

What if I just want to #include LiquidCrystal.h without knowing where it lives?

If i do this:

#include <LiquidCrystal.h>

, then the compiler complains that it cannot find it, so I have to copy LiquidCrystal.h and LiquidCrystal.cpp to my custom library folder and use:

#include "LiquidCrystal.h"

Is there a nicer way?
