make building with Qt4 QGLWidget work again (bug #55735) * acinclude.m4 (OCTAVE_CHECK_QT_VERSION): Also set and substitute QT_OPENGL_CPPFLAGS and QT_OPENGL_LDFLAGS variables. (OCTAVE_CHECK_QT_OPENGL_OK, OCTAVE_CHECK_QT_OPENGL_OFFSCREEN): Add QT_OPENGL_CPPFLAGS to CPPFLAGS for tests, not QT_CPPFLAGS. * libgui/graphics/module.mk %canon_reldir%___init_qt___la_CPPFLAGS): Use QT_OPENGL_CPPFLAGS instead of QT_CPPFLAGS. (%canon_reldir%___init_qt___la_LDFLAGS): Also include $(QT_OPENGL_LDFLAGS) in the list.
