The npm install script will attempt to statically link to libzt.a.
You first need Cmake to build the fPIC-version of the libzt.a library.
To build both release and debug libraries for only your host's architecture use make host. Or optionally make host_release for release only. To build everything including things like iOS frameworks, Android packages, etc, use make all. Possible build targets can be seen by using make list. Resultant libraries will be placed in /lib:
brew install cmake
(cd ../.. ; make clean; make update && make patch && make host_release CC=clang CXX=clang++)
npm install
npm start
Typical build output:
lib
├── release
| └── linux-x86_64
| ├── libzt.a
| └── libzt.so
| └── macos-x86_64
| ├── libzt.a
└── debug
