Thanks for that, I really appreciate your involvement.

I have here:

ii  xlibmesa-gl-dev 4.2.1-12.0.1

I have here:

$ locate GL/gl.h
/usr/include/GL/gl.h
/usr/X11R6/include/GL/gl.h
$ dpkg -S /usr/include/GL/gl.h
xlibmesa-gl-dev: /usr/include/GL/gl.h

Do you have the same at your system?

Notice that xlibmesa-gl-dev provides also the include file above.

Actually, mesa-common-dev depends on mesag-dev which on its turn provides
libgl-dev.  This is the reason octaviz built in your laptop, otherwise the
build-dependencies would not have been fulfilled.

No, this is not necessary, according to my explanation above.  I am puzzled
about the failure to build in your desktop machine.
