A)
remove two duplicate definitions in gtk-hotkey-info.h

B)
Add this to configure.m4
GOBJECT_INTROSPECTION_CHECK([1.30.0])

C)
Add the below to src/Makefile.am

include $(INTROSPECTION_MAKEFILE)
INTROSPECTION_GIRS =
INTROSPECTION_SCANNER_ARGS = --add-include-path=$(srcdir)
INTROSPECTION_COMPILER_ARGS = --includedir=$(srcdir)

  GtkHotkey_1_0_gir_FILES = $(introspection_sources)
  INTROSPECTION_GIRS += GtkHotkey-1.0.gir

  girdir = $(datadir)/gir-1.0
  gir_DATA = $(INTROSPECTION_GIRS)

  typelibdir = $(libdir)/girepository-1.0
  typelib_DATA = $(INTROSPECTION_GIRS:.gir=.typelib)

  CLEANFILES = $(gir_DATA) $(typelib_DATA)
endif
