# CMake Options

To change these options, add `-DOPTION_NAME=NEWVALUE` to the command line.

- On Qt Creator, go to Project -> Current Configuration

Notes:
- Defaults are marked per-platform.
- "Non-UNIX" just means Windows/MSVC and Android (yes, macOS is UNIX
- Android generally doesn't need to change anything; if you do, go to `src/android/app/build.gradle.kts`
- To set a boolean variable to on, use `ON` for the value; to turn it off, use `OFF`
- If a variable is mentioned as being e.g. "ON" for a specific platform(s), that means it is defaulted to OFF on others
- TYPE is always boolean unless otherwise specified
- Format:
  * `OPTION_NAME` (TYPE DEFAULT) DESCRIPTION

  * Note that using **system Qt** requires you to include the Qt CMake directory in `CMAKE_PREFIX_PATH`, e.g:
    * `-DCMAKE_PREFIX_PATH=C:/Qt/6.9.0/msvc2022_64/lib/cmake/Qt6`
- `YUZU_QT_MIRROR` (string) What mirror to use for downloading the bundled Qt libraries
