Perhaps this is most easily done with

export -UT CMAKE_PREFIX_PATH="${ZPFX:+$ZPFX:}$CMAKE_PREFIX_PATH"
cmake_prefix_path

I was hoping for some miracle but yes, that's apparently the best method, with a drawback– it's the longer variable that has to be wrapped in ${…:+}, making the line quite long/dense…
