#### Setup
Clone and initialize the Dusklight repository
```sh
git clone --recursive https://github.com/TwilitRealm/dusklight.git
cd dusklight
git pull
git submodule update --init --recursive
```

#### Building

**CLion (Windows / macOS / Linux)**

Open the project directory in CLion. Enable the appropriate presets for your platform:

![CLion](../assets/clion.png)

**Visual Studio (Windows)**

Open the project directory in Visual Studio. The CMake configuration will be loaded automatically.

**ninja (macOS)**

```sh
cmake --preset macos-default-relwithdebinfo
cmake --build --preset macos-default-relwithdebinfo
```

Alternate presets available:
- `macos-default-debug`: Clang, Debug

**ninja (Linux)**

```sh
cmake --preset linux-default-relwithdebinfo
cmake --build --preset linux-default-relwithdebinfo
```

Alternate presets available:
- `linux-default-debug`: GCC, Debug
- `linux-clang-relwithdebinfo`: Clang, RelWithDebInfo
- `linux-clang-debug`: Clang, Debug

**ninja (Windows)**

```sh
cmake --preset windows-msvc-relwithdebinfo
cmake --build --preset windows-msvc-relwithdebinfo
```

Alternate presets available:
- `windows-msvc-debug`: MSVC, Debug
- `windows-clang-relwithdebinfo`: Clang-cl, RelWithDebInfo
- `windows-clang-debug`: Clang-cl, Debug

#### Running
Pass the disc image as a positional argument. Supported formats: ISO (GCM), RVZ, WIA, WBFS, CISO, GCZ
```sh
build/{preset}/dusklight/path/to/game.rvz
```
If no path is specified, Dusklight defaults to `game.iso` in the current working directory.
