Comparing with https://build.ros2.org/job/Lbin_uR64__gz_rendering_vendor__ubuntu_resolute_amd64__binary/2/consoleText which built successfully, I see that we're missing libegl-dev.

Probably the canonical package here is libgl-dev, note that libegl-dev depends on "
Depends: libegl1 (= 1.7.0-1build1), libgl-dev, libx11-dev"

maybe it's coming from the <depend>opengl</depend> in gz_ogre_next_vendor's package.xml?

If gz-rendering explicitly depends on opengl, I think we should add the same depend to its package.xml, but also something to packages.apt

in rosdistro's rosdep/base.yaml, it looks like the opengl dependency is mapped to [libgl1-mesa-dev, libglu1-mesa-dev]

I split 845ae40 into #1292 to make it easier to backport
