Setting GLIB_VERSION_MAX_ALLOWED ensures we get warnings if we use APIs that are newer than our declared minimum glib version. Setting GLIB_VERSION_MIN_REQUIRED ensures that we get warnings if we use APIs deprecated in versions preceeding this. If the latter is omitted then we get warnings for all deprecations in glib, which is undesirable if we want to keep compat with older versions. This avoids a build error with latest glib ./../libvirt-gconfig/libvirt-gconfig-capabilities-cpu-model.c: In function 'gvir_config_capabilities_cpu_model_init': ../../libvirt-gconfig/libvirt-gconfig-capabilities-cpu-model.c:44:13: error: G_ADD_PRIVATE [-Werror] 44 | model->priv = GVIR_CONFIG_CAPABILITIES_CPU_MODEL_GET_PRIVATE(model); | ^~~~~~~~~~~~~~~ Caused by G_TYPE_INSTANCE_GET_PRIVATE being deprecated.
