0.28.0: despite cmake showing missing zlib it did not exit with non-zero exit code

From cmake ouput:
```console

```

Start by examining the CMake configuration checks that report the missing zlib dependency, then compare them with the build target that includes src/cc/libbpf/src/libbpf.c. Reproduce the configuration without zlib and verify that it exits non-zero before compilation begins.
