 ## Configuration

 The library will be compiled and usable on the same host's platform and
 architecture. Here are some CMake flags which could be useful if you need to
 perform cross-compiling.

- **BUILD_DEB_PACKAGE**
-
-    Generate Debian package, defaults to OFF, available under Linux only.
-
- **BUILD_RPM_PACKAGE**
-
-    Generate Red Hat package, defaults to OFF, available under Linux only.
-
- **BUILD_TESTS**
-
-    Build WebRTC unit tests and mocked classes such as `FakeAudioCaptureModule`.
-
- **BUILD_SAMPLE**
-
-    Build an executable located inside the `sample` folder.
-
- **DEPOT_TOOLS_PATH**
-
-    Set this variable to your own `depot_tools` directory. This will prevent
-    CMake from fetching the one matching with the desired WebRTC revision.
-
 - **GN_EXTRA_ARGS**

    Add extra arguments to the `gn gen --args` parameter.
