Can you somehow create an explicit \book{ } block?
Code after a book block will be executed after the PDF has been 
completely written, i.e. really after the score has been processed 
completely. But if you don't write that explicit \book block LilyPond 
will automatically wrap the whole document in one.

\version "2.19.80"

\book {
  \score {
    \new Staff { c' }
  }
}

#(ly:message "I'm executed after compilation")

You'll see from the log that the message is printed only after the PDF 
file has been finished.
