[CMake] newbie question - what targets are supported?

[Doug Reiland]

Thanks. I did mean rules. The module-list is what I was after. I did piece 
together a macro for my gperf files using add_custom_command() last night 
and is working fine. But I want to make sure I am not reinventing the wheel 
here cause I am betting folks coming from make/linux world have hit the same 
things I have.

moving along slowly, it is taking longer than I thought to do this cmake 
porting test, but...
