Example environment setup (adjust paths to your nwaku checkout):
```
export NWAKU_DIR=/path/to/nwaku
export CGO_CFLAGS="-I${NWAKU_DIR}/library"
export CGO_LDFLAGS="-L${NWAKU_DIR}/build -lwaku -Wl,-rpath,${NWAKU_DIR}/build"
export NWAKU_INCLUDE_DIR="{NWAKU_DIR}/library"
export NWAKU_LIB_DIR="${NWAKU_DIR}/build"
```
Such setup would look like this in a `Makefile`:
```Makefile
NWAKU_DIR ?= /path/to/nwaku
CGO_CFLAGS = -I$(NWAKU_DIR)/library
CGO_LDFLAGS = -L$(NWAKU_DIR)/build -lwaku -Wl,-rpath,$(NWAKU_DIR)/build
build: NWAKU_INCLUDE_DIR ?= $(NWAKU_DIR)/library
build: NWAKU_LIB_DIR ?= $(NWAKU_DIR)/build
build: ## Your project build command
go build ./...
```
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.
