🧑‍🌾 Rendering Main failing after gz-cmake forward port

[Crola1702]

Environment

• OS Version: Ubuntu jammy
• Source Build

Description

• Expected behavior: Build should pass
• Actual behavior: Build is failing

After gazebosim/gz-cmake#399, gz-rendering7 was broken. @mjcarroll solved this issue for rendering7 branch.

The change that broke rendering7 was forward ported in gazebosim/gz-cmake#401, so it makes sense that the issue is happening on main branch.

Steps to reproduce

1. Run a build in https://build.osrfoundation.org/job/gz_rendering-ci-main-jammy-amd64/
2. See it fail.

Output

Reference build: https://build.osrfoundation.org/job/gz_rendering-ci-main-jammy-amd64/24/
