Master build failing

This is on the master branch. The build has failed for me on MacOS all day… Anyone else getting this?

There are a string of errors like this…

[ 50%] Building CXX object source/blender/usd/CMakeFiles/bf_usd.dir/intern/

mac does not have the USD libs yet i think, in your CMakeCache.txt file try turning off WITH_USD
