[CMake] FindXXX capitalization recommendation for new modules

[Daniele E. Domenichelli]

Hello,

I tried to find this out, but I cannot find a clear answer to this 
question: what are the capitalization recommendation when writing a 
_new_ module?

Let's say the library name is "Xxxxx"

The module file should be FindXxxxx.cmake or FindXXXXX.cmake?
The variables
- Xxxxx_FOUND or XXXXX_FOUND?
- Xxxxx_INCLUDE_DIRS or XXXXX_INCLUDE_DIRS?


Thanks


Regards,
  Daniele
