Directory already configured, exiting Meson. Just run your build command
(e.g. ninja) and Meson will regenerate as necessary. If ninja fails, run ninja
reconfigure to force Meson to regenerate.

If build failures persist, manually wipe your build directory to clear any
stored system data.

To change option values, run meson configure instead.
