# Prebuild OCCT for x86_64-unknown-linux-gnu using the manylinux_2_28 base
# image. manylinux_2_28 is AlmaLinux 8 with glibc 2.28, which gives us static
# libraries that link cleanly against any distro with glibc 2.28+ (Ubuntu
# 18.10+, Debian 10+, RHEL/Rocky/AlmaLinux 8+, Fedora 29+, Arch, openSUSE
# Leap 15.1+). Same portability strategy Python wheels use.
#
# The image ships gcc (C++17 capable), cmake, make, curl, and git out of the
# box. Rust is NOT bundled, so we install it via rustup.
