You will need to be careful with those drivers as they are up to 5A of current. Max for CREE LEDs is 1A or 1.5A for XML

In order to use those with CREE LEDs you would have to have at least 5 strings of LEDs in parallel to get that current down to an acceptable level. However you would need to plan on having more of that as if one LED failed in a string it would cause all the other LEDs to blow from over current.

Another limiting factor there is the voltage. Those drivers only put out a maximum of 12 volts. Each Cree LED has a forward voltage of approx 3.2 volts running at maximum power. So per string you could only have approx 4 LEDs. You are looking at a maximum of approx 24 LEDs per driver (6 parallel strings of 4 leds)
