Yes currently that's the case if you use the CMake-provided "NSIS.template.in"
but...

1) Copy the current NSIS.template.in in your project.
    and update it the way you like.

2) update CMAKE_MODULE_PATH
    list(APPEND CMAKE_MODULE_PATH ${CMAKE_SOURCE_DIR}/packaging)

    in order to make your NSIS.template.in in the CMAKE_MODULE_PATH
    (you can even use CPACK_MODULE_PATH)

3) run-rerun packaging an dmake sure that cpack is using your projevtc specific
    NSIS.template.in
