Then, apparently OpenGL is not really feasible with the gtk build we are
doing... from cmake/OpenCVFindLibsGUI.cmake:
|# --- OpenGl ---
|ocv_clear_vars(HAVE_OPENGL HAVE_QT_OPENGL)
|if(WITH_OPENGL)
| if(WITH_WIN32UI OR (HAVE_QT AND QT_QTOPENGL_FOUND) OR HAVE_GTKGLEXT)
| find_package (OpenGL QUIET)
| if(OPENGL_FOUND)
We are not building with Qt (ISTR there were good reason for not do it)
and instead we are building with GTK3. Now, that HAVE_GTKGLEXT is:
| if(WITH_OPENGL AND NOT HAVE_GTK3)
| CHECK_MODULE(gtkglext-1.0 HAVE_GTKGLEXT)
| endif()
So apparently it can never be set with GTK3…
Also, apparently I can't remember why I added that check last year, but
given the current status I'm going to just drop it, as it's not useful
to anybody.
