MacOS compile from source error

Hi! I am trying to compile from source but I keep getting an error from linker saying library not found for -lshm. What is this missing library and how do I fix it? Thanks!

Here is the complete dump:

sudo MACOSX_DEPLOYMENT_TARGET=10.13 CC=clang CXX=clang++ python3 setup.py install
