## This is a blander build based on wayland branch by Christian Rauch
## See Blender thread https://devtalk.blender.org/t/wayland-and-egl-support/11171
## This PKGBUILD was mainly taken from blender-develop-git AUR package.

# Sometimes blender.org takes some time to release patch releases and because Arch users
# are impatient, we sometimes need to build from git directly.
# Update because I get so many queries on this:
# Due to our other rolling deps, it's sometimes not possible to build Blender stable releases.
# More often than not, a new openshadinglanguage breaks it and I could either backport fixes
# or simply roll with a new version. I usually choose the latter when the former seems
# unreasonable.

# For legal reasons, we can't separately package the Optix headers so we'll
# just build the package against them. I checked with NVIDIA and this way is
# fine with them.
