Capillary J reported that Linux build is broken

Indeed, Linux and macOS builds are far behind the current Windows build. The error message is about the lack of precompiled libraries. Backup of the build log:

[TzuChieh]

Current status: fixing build errors and warnings

[TzuChieh]

Engine now compiles properly using GNU compiler (g++ 14.0.1). Now working on editor.

[TzuChieh]

All unit tests passed. All render tests passed. CLI and editor both working properly.

[TzuChieh]

All tasks are done. Awaiting Capillary J to confirm.
