cmExprParser is just for the math() command.  The language parser
is "cmListFileLexer.in.l" and "cmListFileCache.cxx".  Tracking of
the current source file may need to be moved.  The lexer would have
to recognize #line syntax and update lexer->line.  Be careful to
only do so in the main state and not inside a quoted or bracket
argument.
