Thanks for the report.

Gianfranco Costamagna actually highlighted this on #debian late last
week, and I already have a fix in the works.  The problem's really in
libwxgtk3.0-dev, which has: 

Suggests: wx3.0-doc, libstdc++-dev, gettext, libgl1-mesa-dev | libgl-dev, xlibmesa-glu-dev | libglu-libdev

I'm unclear why this seemed like a good idea (it predates my involvement
in wx maintainership and the git log doesn't enlighten) but I'm guessing
someone wanted to avoid forcing these extra build-time dependencies on
everyone, when they're only needed by those building packages using
classes like wxGLCanvas.  But since we appear to pull them in indirectly
on Debian anyway, it seems best just to pull them in explicitly rather
than add another package like libwxgtk-gl3.0-dev.
