music = { b1 }
\version "2.23.3"

includeFunction = #(define-void-function (filename) (string?)
                     (ly:parser-parse-string (ly:parser-clone) (ly:gulp-file filename)))

%% or alternatively

includeFunctionB = #(define-void-function (filename) (string?)
                     (ly:parser-parse-string (ly:parser-clone) (format "\\include \"~a\"" filename)))

%\include "includetest.ily"

\includeFunction "includetest.ily"
