As per upstream docs "#include <glibmm.h>" is the correct usage,
the "glibmm-2.4" directory is handled correctly via pkg-config:
$ pkg-config --cflags glibmm-2.4
-I/usr/include/glibmm-2.4 [...]
#ifndef PULSEVIEW_PV_PROP_BINDING_BINDING_H
#define PULSEVIEW_PV_PROP_BINDING_BINDING_H
-#include <glibmm-2.4/glibmm.h>
+#include <glibmm.h>
#include <vector>
#include <memory>
#ifndef PULSEVIEW_PV_PROP_PROPERTY_H
#define PULSEVIEW_PV_PROP_PROPERTY_H
-#include <glibmm-2.4/glibmm.h>
+#include <glibmm.h>
#include <functional>
#include <QString>
