#### Linux

For Linux, you will also need to build the Linux SDK with the cmake options
below.

```bash
--extra-cmake-options=-DSWIFT_BUILD_RUNTIME_WITH_HOST_COMPILER=FALSE,\
-DCMAKE_AR=<path to llvm-ar>,\
-DCMAKE_RANLIB=<path to llvm-ranlib>,\
-DSWIFT_SDKS='LINUX;WINDOWS',\

-DSWIFT_WINDOWS_x86_64_ICU_UC=<path to ICU UC lib>
```
For Linux, you will need to build the Linux SDK instead of the macOS SDK by
replacing the cmake option with `-DSWIFT_SDKS='LINUX;WINDOWS'`.
