Cadwr is not listed as a King of Builth, according to http://www.historyfiles.co.uk/KingListsBritain/CymruBuilth.htm
Builth (Buellt)

The kingdom was centered on Caer Bedris in Builth, in modern Powys. It was apparently founded as an offshoot of Powys by the Powysian Vortigern's son. Apparently his claim was confirmed by Ambrosius Aurelianus at Caer Gloui after Vortigern's death.
The sub-kingdom or region of Gwrtheyrnion was part of Builth's territory, and the kings often seem to bear the title king of Guorthegirnaim (Gwrtheyrnion).
One of the results of the messy situation in the east, following the Jutish foederati takeover of Ceint and the death of Vortigern, is that Gwrtheyrnion now passes to his sole surviving (legitimate) son. Nennius states that this is 'granted' by Ambrosius Aurelianus, but it is probably little more than a rubber stamp. Pascent governs the principality directly from Builth, although he has probably already exercised regional control over it from the point at which it had first been divided from Pagenses. In fact, it would seem that Pacent is already deceased by this time and that it is his son, Braciat, who now governs Built and Gwrtheyrnion - a fine detail that may have been lost to some chroniclers.

Fernvail / Ffernfael ap Tewdr
Last king of Builth & Gwrtheyrnion
by 800 Fernvail's fate is unknown, as are any firm dates for his life and reign. If the estimate of AD 745 for the start of his reign is remotely accurate then it is unlikely that he lasts as long as 800, but other estimates place him around this later period. A collection of medieval genealogies held in the Bodleian at Oxford - Jesus College MS20 - show him as a contemporary of Arthfael Hen ap Rhys of Glywyssing (Arthfael md. his cousin, Brawstudd, but presumably early in his life rather than later).
This king can be placed anywhere in the last quarter of the eighth century and first quarter of the ninth century, so using AD 800 as a rough point for the presumed death of Fernvail seems appropriate. Afterwards, Builth and Gwrtheyrnion cease to exist as separate Welsh territories in their own right, being absorbed by Seisyllwg and then Deheubarth. The precise circumstances and process by which this happens are unknown.
