 - Toolchain: Default should be fine
 - Generator: Ninja
 - CMake options: You want to duplicate the essential CMake flags that `build-script` had used here, so CLion understands the build configuration. You can get the full list of CMake arguments from `build-script` by providing the `-n` dry-run flag; look for the last `cmake` command with a `-G Ninja`. Here is a minimal list of what you should provide to CLion here for this setting:
-    - `-D SWIFT_PATH_TO_CMARK_BUILD=SOME_PATH/swift-project/build/Ninja-RelWithDebInfoAssert/cmark-macosx-arm64 -D LLVM_DIR=SOME_PATH/swift-project/build/Ninja-RelWithDebInfoAssert/llvm-macosx-arm64/lib/cmake/llvm -D Clang_DIR=SOME_PATH/swift-project/build/Ninja-RelWithDebInfoAssert/llvm-macosx-arm64/lib/cmake/clang -D CMAKE_BUILD_TYPE=RelWithDebInfoAssert -G Ninja -S .`

     - replace the `SOME_PATH` to the path where your `swift-project` directory is
     - the CMAKE_BUILD_TYPE should match the build configuration name, so if you named this profile `RelWithDebInfo` the CMAKE_BUILD_TYPE should also be `RelWithDebInfo`
     - **Note**: If you're using an Intel machine to build swift, you'll need to replace the architecture in the options. (ex: `arm64` with `x86_64`)
