[CMake] Passing Macro Arguments to "configure_file"

[Michael Jackson]

Thanks for the clarification on that. I did figure out the set  
(variable ${varaible}) part though as a work-around.
   Just my opinion but that is not very intuitive. Now that I know how  
to deal with it I guess it is ok.

Thanks
