If you'd like to try a patch, the relevant code is in
Source/cmExprParser*. Add a callback for #line nnn and update the
CurrentLine variable cmExprParserHelper.cxx. Don't forget tests :) .

This will also likely need a policy since there's no guarantee that
#line "directives" don't exist in already existing code as comments.
