In commit 0c539a0 you wrote "Back up manifold upgrade - looks like we're not ready for 3.0 yet": what is the problem exactly?
I'm trying to install BRL-CAD on FreeBSD, and while manifold v3.0.1 from @elalish compiles without error and all tests pass, the version v2.4.5 included in bext fails, because Thrust is not supported on FreeBSD, and it seems that it cannot be deactivated.
