burn-app is ancient software; it hasn't been updated since 2011. It uses QTKit, which Apple has deprecated. Apple no longer includes the QTKit headers in macOS 10.12 or later, which is why it fails to compile for you on 10.13. Compiling this software on 10.12 or later is possible using the OS X 10.11 SDK or older, but Xcode on 10.12 and later don't include the 10.11 SDK or older. I have been working on a way to make macOS SDKs available in MacPorts. Once that's done, we can apply a fix to this port to use an older SDK.
