You specified @ONLY option which means that only @VARNAME@ will be processed

Either you drop the @ONLY option of configure_file or you write
#cmakedefine FOO_DEFINE @SOME_CMAKE_VARIABLE@
and you should get what you want.
@ONLY is very useful when you configure some kind of shell script template
where $ shoudn't be interpreted by CMake condigure_file because it's meant
to kept
as is in the resulting configured file.
