SON OF USD BUILD CLUB

Building a native Apple Silicon version of UsdView

This version of UsdView will have an Apple Silcon, Metal-native viewer, openimageio, and alembic support. It does not yet include MaterialX, OpenColorIO, or any of the other many options build_usd.py supports.

Successfully get usdview running on conda and M1 as follows:

by our incantations we manipulate the dance of electrons in the microcosm, the very fabric of the universe itself

.? is equivalent to orelse unreachable. So to unwrap you can either do const y = x orelse <default>; or if (x) |unwrapped_x| {};

One way to debug ZLS lookups is to do zig run zls/zig-out/bin/build-runner.zig --pkg-begin "@build@" path/to/your/build.zig --pkg-end and make sure it outputs a list of packages.

boost removal is an ongoing, low noise effort.

At this point, if you build without python, you can build the usd libraries treating boost as header only, without actually building boost. one or two of the command line tools use boost for command line options.

Porting those to (my suggestion) CLI11 would remove the last non-python boost dependency.

to be redundant and clear: you can manually cherrypick the boost headers
