Because of the differing flexibility and rate of expansion/contraction, it's best to use a flexible latex adhesive.
If it's a floor, then a thing called a 'de-coupling membrane' is advised. Although they've managed to overcomplicate things with many different types available. Basically, it's a net that prevents cracking from movement.
