vcpkg install should deploy ThirdPartyNotices.txt

When I install cpprestsdk with vcpkg as per the docs, I don't get the _ThirdPartyNotices.txt_ from the repo, only _license.txt_ renamed as _copyright_.

Would you please update the vcpkg install (sic: the cmake install) to distribute this file also? This would greatly aid in us meeting our legal requirements when we ship software containing cpprestsdk.
