Library used by both MegaChat client and server. Probably it will be a static library or maybe source code will be simply included in applications.

To build project you can simply run ./run.sh build at the project root.

Or you can build manually

mkdir buld
cd build
cmake ..
make

To run tests ./run.sh run-tests

Or launch binary at BULD-DIR/tests/test-megachat-networklib
