Source: opencv
Version: 2.4.9.1+dfsg1-2

There should be missing an "else" in debian/rules which implies
WITH_OPENGL is always ON for ubuntu (overriding previous if-else
statement) and always undefined for other distributions.

Here is the fix:

That's also true for the version in experimental (which is the one we
care about, as we're "about" to do a transition to it.

ISTR the KDE/Qt team wants to also apply that change that is done in
ubuntu in debian as well, and also something about arm64.  I'd like to
ask them about this, maybe that "if ubuntu" check should be
dropped.

Thanks for the patch!

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.
