Linking OpenGL apps

[Alec Leamas]

Dear list,

Im probably missing something simple... that said, I'm trying to flatpak
a somewhat large application opencpn which uses OpenGL. As I understand
it, the flatpak sandbox should support this.

Alas, when I try to locate the OpenGL headers and libraries my cmake
configuration script cannot find it. I have tried to build both against
the org.freedesktop.Platform and org.gnome.Platform with the same result.

Looking into the situation using a sandbox shell I indeed cannot find
any relevant OpenGL files under /app/include and /app/lib.

What's the story here? Am I supposed to link against the hosts's GL
libraries? Or?
