This PR changes AEC_INCLUDE_DIRS (which is undefined) to AEC_INCLUDE_DIR (which is defined) in src/CMakeLists.txt. I think this wasn't creating problems in the CI because we're using the apt-installed libaec, so it's in the system-wide include path.
Also fixing a CI failure related to the PNG_ARM_NEON option for MacOS.yml. Not sure why this is only just happening.
