# --- GTK ---
These changes introduce Gtk3 support into the highgui module. A new option WITH_GTK3 has been added to the cmake configure system to enable compilation under Gtk version 3.The flag HAVE_GTK3 is also introduced to select the new Gtk3 code in the source files. (Gtk2 is disbled when Gtk3 is selected). window_gtk.cpp has been modified to remove obsolete (and deleted from libgtk 3) and introduce new Gtk3 code in its place when compiled for Gtk3. To compile for Gtk2, disable WITH_GTK3 in cmake. To build for Gtk3 both WITH_GTK and WITH_GTK3 must be selected.

if(WITH_GTK AND NOT HAVE_QT)
Improve GTK+ library selection logic. The new logic will select GTK+3 by default if WITH_GTK is selected. If the GTK+3 libraries are not found, then GTK+2 libraries will be selected if found. This can be overridden by using WITH_GTK_2_X to force selection of GTK+2 (if found).

ocv_check_modules(GTHREAD gthread-2.0)
Correct error with GTK3 not found selection When GTK3 is not found, HAVE_GTK was being set to TRUE. This edit ensures that HAVE_GTK is only set if GTK3 or GTK2 (meeting minimum version requirements) is present. Selection logic for printing 'GTK: No' when the libraries are not found has also been removed so the message is printed when GTK is not found or selected in common with other libraries.

Use GTK_VERSION_MAJOR to switch between GTK+ version two and three specific code. As a result of this, HAVE_GTK3 no longer needs to be exposed. The use of HAVE_GTK, and HAVE_ GTK3 have been changed to mirror the method used by HAVE_QT and HAVE_QT5.

Disable OpenGL when Gtk3 is selected The OpenGL library is not supported on Gtk3 which uses the cairo library for rendering. Cairo, in turn uses hardware acceleration when supported by the underlying system. Some improvement to performance may be gained by useing the cairo-gl and cairo-glx libraries included on modern Gtk3 systems. See the cairo documentation for further information. The following link may also be of interest. http://lists.cairographics.org/archives/cairo/2012-October/023609.html

Refactored detecting several Apple-related technologies. Now the HAVE_* macros are set using cvconfig.h. Previously most of them already were there, but were always undefined. One, HAVE_COCOA, I had to add. This also makes the CMake code more consistent; now, WITH_* variables are always checked in cmake/*, while HAVE_* variables are checked in modules/highgui/CMakeLists.txt.
