| ## Controlling subproject dependencies with `dependency(allow_fallback: ...)` | |
| As an alternative to the `fallback` keyword argument to `dependency`, | |
| you may use `allow_fallback`, which accepts a boolean value. If `true` | |
| and the dependency is not found on the system, Meson will fallback | |
| to a subproject that provides this dependency, even if the dependency | |
| is optional. If `false`, Meson will not fallback even if a subproject | |
| provides this dependency. |
