ci-windows.yml

# This is a copy of ci-unix-static.yml for Windows. It differs from ci-unix-static.yml as follows:
#
#   * The os matrix consists of windows-latest only.
#   * Installs Visual Studio in the os image.
#   * Doesn't install cmake 3.17.x, because only cmake 3.18 or later, with the
#     following bug fix, detects Visual Studio compilers correctly:
#     https://gitlab.kitware.com/cmake/cmake/-/issues/20585
#   * Runs ext/*.cmd as Windows batch files rather than using bash. This is
#     important for ext/svt.cmd, to prevent it from running ext/svt.sh.
#   * Builds with local libjpeg (-DAVIF_JPEG=LOCAL).
#   * Builds with local zlib and libpng (-DAVIF_ZLIBPNG=LOCAL).
