Hi, Amrein.

If U++ uses GTK3 only, x11 or libnotify are not required.
<..>
So if I'm not wrong, this part of the patch is incorrect:
<..>
and should be replaced by
-pkg_config((LINUX | FREEBSD) !X11) "gtk+-3.0 libnotify";
+pkg_config(POSIX !X11 (!OSX | OSX11)) "gtk+-3.0 libnotify";
If use
pkg_config(POSIX !X11 (!OSX | OSX11)) "gtk+-3.0 libnotify";
or
pkg_config(POSIX !X11 (!OSX | OSX11)) "gtk+-3.0";
in uppsrc/CtrlCore package to build examples/AddressBook for GUI main package configuration, then there is following linker error:
Linking...
/usr/bin/ld: undefined reference to symbol `XFlush' (try adding -lX11)
//usr/local/lib/libX11.so.6: could not read symbols: Bad value
c++: error: linker command failed with exit code 1 (use -v to see invocation)
The XFlush function is used in GetProperty function in uppsrc/CtrlCore/GtkX11Util.cpp file for GUI_GTK define. This is why !X11 (GTK 3) case requires x11 pkg-config dependency (at least on FreeBSD, where other specified pkg-config dependencies didn't include x11 implicitly).

Some example of pkg-config output for libnotify and x11 on FreeBSD 10.4:
% pkg-config -cflags -libs libnotify
-I/usr/local/include -I/usr/local/include/gdk-pixbuf-2.0 -I/usr/local/include/glib-2.0 -I/usr/local/lib/glib-2.0/include -pthread -L/usr/local/lib -lnotify -lgdk_pixbuf-2.0 -lgio-2.0 -lgobject-2.0 -lglib-2.0 -lintl
% pkg-config -cflags -libs x11
-I/usr/local/include -D_THREAD_SAFE -pthread -L/usr/local/lib -lX11
Edit:
But after build test for reference/TrayIcon package, there was following linker error:
<..>/CtrlLib/CLANG.Gui.Shared/CtrlLib.a(TrayIconGtk.o): In function `Upp::TrayIcon::Message(int, char const*, char const*, int)':
<..>/upp/uppsrc/CtrlLib/TrayIconGtk.cpp:(.text._ZN3Upp8TrayIcon7MessageEiPKcS2_i+0x1b): undefined reference to `notify_is_initted'

<..>/upp/uppsrc/CtrlLib/TrayIconGtk.cpp:(.text._ZN3Upp8TrayIcon7MessageEiPKcS2_i+0x77): undefined reference to `notify_notification_show'
c++: error: linker command failed with exit code 1 (use -v to see invocation)
where mentioned functions are used in TrayIcon::Message method in uppsrc/CtrlLib/TrayIconGtk.cpp file.
This may mean, that libnotify package dependency is required for some cases in uppsrc/CtrlLib package.
Possible to add following check for uppsrc/CtrlLib package:
pkg_config(POSIX !X11 (!OSX | OSX11)) libnotify;
Example of ldd output for TrayIcon and AddressBook executables for this case, which library dependencies are the same:
