[CMake] Nested variable substitution

[andrew.blose at kodak.com]

  FOREACH (MY_VAR FOO)
    SET(FOO_DBL_EXP "BAR")
    SET(MY_VAR_PRIME  "@${MY_VAR}_DBL_EXP@")
    MESSAGE("MY_VAR_PRIME: ${MY_VAR_PRIME}")
  ENDFOREACH (MY_VAR)

Maybe I'm missing something obvious but... 

On the windows platform, why does the previous snippet of CMAKE code 
generate:

MY_VAR_PRIME: BAR

with CMAKE invoked from the command line and

MY_VAR_PRIME: @MY_VAR_PRIME@

when invoked through CMakeSetup.exe?

Thanks
