2.8.4 and it will probably not even change on Harmattan

Not sure what you mean by this, but the proposed alternative way seems
to also be a cmake version dependent deal. From the documentation:
"...CMake 2.6 introduced support for exporting targets from one
project and importing them into another...". However I think it is
achievable...Not sure about the version difference aforementioned.

Mmm, so it seems a bit controversial to me. You mentioned that above
it is bad if the map is nearby the treasure. However, it seems to
still be the situation since Gluon will install it. I thought that the
only way is that if it is independently installed from Gluon since
that way, it exists anytime. This is still a bit confusing to me.
Could you please clarify ? Thank you!
