Yes. This should be similar to target_link_libraries() and 
target_link_libraries( LINK_INTERFACE_LIBRARIES ), right ?
It could be named INTERFACE_INCLUDE_DIRECTORIES...
It might also need to separate between those include directories used when 
linking against the library within the same project, and when linking against 
the library once it has been installed along with its headers.
