This works as expected in the Flatpak build:
flathub/com.bambulab.BambuStudio#86

The Windows and Mac build failures don't seem to be related.

@hadess What benefits does upgrading to GLEW 2.3 bring? I checked the original Git history and it appears the version is 2.2.

It’s still unclear whether the build errors on macOS 15 are related, but the errors on Windows are clearly relevant. OpenCSG depends on GLEW, and it looks like there are some linking issues.

I removed the 2.3.0 update, I guess there's not much point in updating it if there are no relevant changes.

It’s still unclear whether the build errors on macOS 15 are related, but the errors on Windows are clearly relevant. OpenCSG depends on GLEW, and it looks like there are some linking issues.

I think that the copy-pasted version built static libs, whereas upstream creates shared libraries by default, let's see if this works.
