pointAndClickOff in a "book file"

[Federico Bruni]

I have a file (for a book) which includes several files (each piece of music).

point-and-click is enabled in each of the single files and I want to keep it.

But when I create the book I don't care for point-and-click.

I'd like to keep the pdf smaller and compile it faster..

There's a way to tell LilyPond to disable point-and-click just in the book file?

I've tried:

#(ly:set-option 'point-and-click #f)

but it's not working.

Thanks for your help,

Federico
