Linux build

Hi , We are trying to integrate Lyra into our webrtc server running on linux and compiled using Make .

I have tried to generate linux build by using the below command

```
bazel build --enable_platform_specific_config lyra:lyra_encoder
```

But it generates only .so and .a files in bazel-bin folder . How to generate include folders too ?

Also i tried to add include files in a separate folder and linked liblyra_encoder.so and other liblyra_*.so files , but it throws undefined reference error in absl,glog libraries .

How to get a single lyra.so file with all other libraries linked ( Like a output from cmake/make)?
