# Builds libavif with local aom and dav1d and runs fuzztest tests
# (tests that have 'fuzztest' in their name).
# They are run in "unit test mode" (run with random inputs for a short period of time)
# see https://github.com/google/fuzztest/blob/main/doc/quickstart-cmake.md
# Runs on ubuntu only. libavif is built with clang.
