Compilation errors on Linux.

I understand that this project may not be targeted to Linux. I'm just putting this information here for anyone who may be interested.

any support for linux? I am facing similar issues during compilation

[hyperlogic]

Re-opening, I'll try to get this working. I don't have a true Linux system handy. I'll try under wsl2 or a chromebook.

[hyperlogic]

I just pushed 53825deb8e9d4daad5f1b75a52ef00c4dccf3ea7 on the feature/linux branch. It's not fully tested because I don't have a working Linux install that supports OpenGL 4.6. Also, OpenXR support is explicitly not implemented yet.

Let me know if this does or does not work for you.

[JiamingSuen]

Thanks for your rapid response. It works perfectly (except for the fps indicator which is blank)!

[hyperlogic]

The fps counter doesn't display until 100 frames have rendered, it should show up eventually. The feature/linux branch has been merged into main.
