Build Error - metrics_discovery_helper_dx11.h not found

[anonymous_user_855895fd1 (anonymous_user_855895fd)]

I had to modify D3D11RHI.Build.cs and insert this:

 //Tony; ugh, add the metrics discovery path, so debug builds actually find the bloody headers.
PublicSystemIncludePaths.Add(Target.UEThirdPartySourceDirectory + "IntelMetricsDiscovery/MetricsDiscoveryHelper/build/include/metrics_discovery/");

solved it for everything.
