Target machines - defaults to the build host::
The target machine expresses which machines the application expects to run.
A target machine is identified by its operating system and architecture.
Gradle uses the target machine to decide which tool chain to choose based on availability on the host machine.

The target machine can be configured as follows:

.Configure library target machines

                application {
                    targetMachines = [machines.macOS, machines.linux]
