ExternalProject: Add options to specify BYPRODUCTS (#14963)
The external project's build process may generate byproducts on which
other rules in the driving project's build later depend. Provide a way
for the driving project to specify what byproducts it expects to be made
available by the custom commands that drive the external project.
