Summary:                    Ninja complains about missing rule
Description: 
With the attached example project, Ninja will complain with an error saying 
"ninja: error: 'lib/libmylib.a', needed by 'myapp', missing and no known rule to
make it"

I'm using ExternalProject_Add() and then using imported library targets.
I then set the imported target to depend on the ExternalProject to make sure it
is up to date.

This works fine with Visual Studio, NMake, Make, Xcode, etc....

Steps to Reproduce: 
See attached project.
