For a reference integration, see how `status-go` wires `CGO_CFLAGS` and `CGO_LDFLAGS` in its build setup. For a reference integration, see how `status-go` wires `NWAKU_INCLUDE_DIR` and `NWAKU_LIB_DIR` in its build setup.
NOTE: If your project is itself used as a Go dependency, all its clients will have to follow the same nwaku setup. NOTE: If your project is itself used as a Go dependency, all its clients will have to follow the same nwaku setup.
