The conditionnal includes you can do with LilyPond, which you can trigger
for instance with command line options.

Consider:

includePageLayoutFile = 
#(define-music-function (parser location) ()
   "If page breaks and tweak dump is not asked, and the file
   <basename>-page-layout.ly exists, include it."
   (if (not (ly:get-option 'dump-tweaks))
       (let ((tweak-filename (format #f "~a-page-layout.ly"
                                     (ly:parser-output-name parser))))
         (if (access? tweak-filename R_OK)
             (begin
               (ly:message "Including tweak file ~a" tweak-filename)
               (set! page-layout-parser (ly:clone-parser parser))
               (ly:parser-parse-string page-layout-parser
                                       (format #f "\\include \"~a\""
                                               tweak-filename))))))
   (make-music 'SequentialMusic 'void #t))

which can be found in the file ly/music-function-init.ly of recent
versions of LilyPond.
