Hello, I am following this script by JK Jung for installing opencv in Jetson Nano, just disabling qtand including opencv_contrib. Even though I build it with -D WITH_OPENGL=ON , After generating config, I am getting this
GUI: GTK+: YES (ver 3.22.30)
GThread : YES (ver 2.56.4)
GtkGlExt: NO
OpenGL support: NO
VTK support: NO
Is there any other way of building opencv with opengl support.
How ever when I did:
glxinfo | grep "OpenGL version"
OpenGL version string: 4.6.0 NVIDIA 32.1.0
glxinfo | grep rendering
direct rendering: Yes
GL_NV_path_rendering, GL_NV_path_rendering_shared_edge, GL_NV_path_rendering, GL_NV_path_rendering_shared_edge, GL_NV_packed_float_linear, GL_NV_path_rendering, GL_NV_path_rendering_shared_edge, GL_NV_pixel_buffer_object,
But still when I am building opencv with opengl, it shows -- GUI: -- GTK+: YES (ver 3.22.30)
-- GThread : YES (ver 2.56.4)
-- GtkGlExt: NO
-- OpenGL support: NO
-- VTK support: NO
I am using the following patch as suggested in that article,

Every thing is building well, I am just stuck on this part, Any help ??
