I had the same problem. Running brew install cddlib gmp first fixed this for me. This page suggests this for installing from source, but I also needed it for installing using pip.

[shuoyang2000]

It works for me, thanks a lot Bob! I also need to install use pip as suggested in the document env "CFLAGS=-I$(brew --prefix)/include -L$(brew --prefix)/lib" pip install pycddlib

Yes, all those steps are necessary. Thanks for the help @bobmyhill!
