NODE-GYP Build

If not installed the corresponding library/path cannot be found, in the middle of the header file can not find errors;

Clumsy workaround, add in the makefile below the build

Cxxflags + = -i/usr/include/glibmm-2.4-i/usr/lib/x86_64-linux-gnu/glibmm-2.4/include-i/usr/include/ glib-2.0-i/usr/lib/x86_64-linux-gnu/glib-2.0/include-i/usr/include/sigc++-2.0-i/usr/lib/x86_64-linux-gnu/sigc+ +-2.0/include-i/usr/include/giomm-2.4-i/usr/include/gdkmm-3.0-i/usr/lib/x86_64-linux-gnu/gdkmm-3.0/include-i/ usr/include/pangomm-1.4-i/usr/lib/x86_64-linux-gnu/pangomm-1.4/include-i/usr/include/gtk-3.0-i/usr/include/ Pango-1.0-i/usr/include/cairo-i/usr/include/gdk-pixbuf-2.0-i/usr/include/cairomm-1.0-i/usr/include/freetype2-i /usr/include/gtkmm-3.0-i/usr/lib/x86_64-linux-gnu/gtkmm-3.0/include-i/usr/include/atkmm-1.6-i/usr/include/ atk-1.0-i/usr/include/libnotifymm-1.0

The above libraries are installed according to the error prompts

JavaScript test Code

var notify = require ("./build/release/node_gtknotify");

var notification = new Notify.notification ();

Notification.title = "notification title";

Notification.icon = "Emblem-default"; see/usr/share/icons/gnome/16x16

Notification.send ("Hello,world");

Note that the runtime may have an error message: * * Symbol not found because the corresponding shared link library was not added

Workaround: Add in Build/node_gtknotify.target.mk

LIBS: =-lglibmm-2.4-lnotify-lnotifymm-1.0
