"""Copy the MobileGL dEQP platform port into a VK-GL-CTS checkout.

The port is version-controlled here, in the MobileGL repo, so it survives a
throwaway CTS clone. This drops it into the places VK-GL-CTS expects:

    framework/platform/mobilegl/     <- platform sources
    targets/mobilegl/mobilegl.cmake  <- target definition (-DDEQP_TARGET=mobilegl)

Usage:
    python sync_to_cts.py <path-to-VK-GL-CTS>
