In @.gitlab-ci.yml:
- Line 130: The export OPTIONS variable uses the incorrect SCons option name
D3D12_ENABLED=yes, but the SConstruct file declares the option as d3d12, causing
the build system to silently ignore it and leave D3D12 disabled. Replace all
instances of D3D12_ENABLED=yes with d3d12=yes in the OPTIONS variable on lines
130, 142, 154, and 183 to ensure the Direct3D 12 rendering driver is properly
enabled during the build process.
