 The port causes MacPorts to erroneously emit this warning because the port
 clears the variable `configure.sdkroot`. You need an SDK to build on 10.14
 and later. MacPorts sets `configure.sdkroot` to the path to the SDK. Ports
 should use that variable when they need to obtain the path to the SDK.
 Ports should not clear that variable.
