# This wrap is based closely on the google-brotli wrap.

# ===== NOTE =====
# This is a fork of the wrap available at
# https://wrapdb.mesonbuild.com/google-woff2.
#
# The woff2 encoder relies on the brotli encoder, which contains static symbols
# with the same names in different translation units, so it does not support
# unity builds. Since we only need the decoder, we have simply removed the
# woff2_encoder_dep dependency in order to depend on woff2 without breaking
# unity builds (via the transitive dependency on brotli).
