[CMake] INCLUDE_DIRECTORIES in sub-directories doesn't work?

[Sean Soria]

Include doesn't seem to do what I would expect either.  I want to add
include directories for any files found in foo.  it seems
include_directories doesn't do it because there must be a target in
that directory.  would setting the source property do it?
