From e5cbe66571e020489b1156198fdbefd202aef130 Mon Sep 17 00:00:00 2001 From: Samuel Martin Date: Sun, 5 Jul 2015 23:54:48 +0200 Subject: [PATCH] package/opencv: add opengl support In OpenCV, OpenGL is only used by highgui module. OpenGL support is done using extensions from 3rd party framework: either Qt5OpenGL with Qt5 (with GL support only, not GLES); or gtkglext (which is not available in Buildroot) with gtk2 So, make OpenGL knob a sub-option of the Qt5 support option. Note: we enclose both the GUI toolkit choice and the GL option in an if-block, so that the GL option gets properly indented; having it depend on WITH_QT5 is not enough, because it does not directly follow it, so kconfig would not consider it for indenting.
