Oh, right.  That's annoying.

I'd skip worrying about that for now.  Get a patch working for the
port, then worry later about if/how to upstream it.

    get_property(idirs DIRECTORY ${CMAKE_CURRENT_SOURCE_DIR} PROPERTY INCLUDE_DIRECTORIES)
    set(CMAKE_REQUIRED_INCLUDES ${idirs})

seems like it might do the trick.
