use external modules library in driver using CMake

[dornbirndevelops]

Hi, quick question regarding library integration.
I'm developing a sensor driver foo_impl.c that is supposed to use symbols declared in foo.h which in turn are implemented by foo.c.

zephyrproject/
├─ modules/lib/foo/
│  ├─ foo.h
│  ├─ foo.c
│  ├─ CMakeLists.txt
│  ├─ zephyr/
│  │  ├─ module.yml
├─ zephyr/drivers/sensor/foo/
│  ├─ foo_impl.c

How does the implementation of CMakeLists.txt need to look like, so I can use the module library in Zephyr?
