I think @CMAKE_SOURCE_DIR@ would have worked just fine as well. cmake's 
configure_file command works with both formats. I don't know why John chose 
the shell-like variable notation.

But yes, the changes were necessary to get configure_file to work. It would 
not work with the @-...-@ notation.

You can probably use
sed -es/'${CMAKE_SOURCE_DIR}'/${top_srcdir}/g

The single quotes around ${CMAKE_SOURCE_DIR} will prevent bash from expanding 
it on the spot. bash will still remove them so sed will see
-es/${CMAKE_SOURCE_DIR}/<bash-expanded-value-of-${top_srcdir}>/g
