Please find your fixture file included.
Note that it seems most of the cameo fixture were already included in cuety.
For the botex and stairville dimmer pack youw on't be able to use them as it in cuety as it's using subfixtures that cuety do not manage. The best solution is to patch each time 4 units of 1ch dimmer pack you can find in the "generic" manufacturer.
Or if you want to save some "fixtures" you can patch 4ch rgbw par still from generic and you will control each chanel of your dimmer pack with red, green, blue and white parameters.
Enjoy
