noob question on Generic Event Extension

[Dhoti Walla]

Hi,

I'm playing around with X source code so I can learn more about X.

I've downloaded the latest xorg server source and successfully built it. 
However I find that Generic Event Extension is not being included in the 
build.

How do I enable Generic Event Extension?

thanks for all help

is the correct forum?
