There is no generic solution for this. In your case I'd suggest a dummy
mesalib package, that redirects the dependency to your OpenGL package:
A makefile with just "PACKAGES-$(PTXCONF_MESALIB) += mesalib" and an
in-file that selects your package.
However, this won't generate any ipkg dependencies. A solution for this is
on the todo list, but so far not implemented.
