In order to spend a UTXO that is locked with a CLTV, you must set `nLockTime` on your new transaction. Usually, you just want to set it to the present time or the present block, as appropriate. As long the CLTV time or blockheight is in the past, and as long as you supply any other data required by the unlocking script, you'll be able to process the UTXO.
