There is no build script. The failure occurs when the FreeBSD port is built on arm64. The ports framework supplies cmake arguments and environment.

The latest rev. c4921ab from ```feature/clang``` still builds with these SIMD flags: ```-msse4.2 -mfpmath=sse -mavx2 -mfma```.

```-mavx2``` is added elsewhere.

I have opencascade-7.6.0 and it doesn't install ```BRepAdaptor_HSurface.hxx```. It does install a similarly named ```BRepAdaptor_Surface.hxx``` though.

Do you have a branch that supports the latest Open Cascade? The FreeBSD port for Open Cascade has been updated a while ago and now Chrono fails to build.

Is there an ETA?

FYI: OpenCascade-7.4.0 doesn't even build with current cmake. I tried to resurrect the old version and found that it fails to build now.
