Summary:                    External Project cannot set SOURCE_DIR to subfolder
of another External Project
Description: 
I have an External Project that fetches sources from git repo. This repo has
submodules.
I want another External Project to refer this directory. However it does not
work: build script generated by cmake fails on first start.

If SOURCE_DIR for dependent External Project refers to SOURCE_DIR of main
External Project it works.

It looks like build system generated by CMake attempts to validate directory,
but it cannot simply because there is no way CMake could now of project
structure.
