This doesn't quite make sense to me. The line above that RDEPENDS is
adding a dependency in the opposite direction and will effectively make
one package uninstallable without the other.

The question is does the libgles2-mesa-dev package need the libgles3-
mesa-dev package? If not, this is not the right way to solve the
problem you're seeing.
