Hi, I am not sure if it's right, but I think the dection may need
convert to this:
```
if not get_option('libusb').disabled()
libusb = dependency('libusb-1.0', required: get_option('libusb').auto(),
version: '>=1.0.13', method: 'pkg-config',
kwargs: static_kwargs)
No, Meson knows what to do with feature objects passed to "required".
With Meson 0.59 however it will be possible to write
libusb = dependency('libusb-1.0',
required: get_option('libusb').disable_auto_if(not
have_system),
version: '>=1.0.13', method: 'pkg-config',
kwargs: static_kwargs)
without any if.
