Vala and Snapcraft. Issues with a library part in Vala.

[Luca Dionisi]

This is another solution that I thought of.
I want to put the library mylib-y (the one that is needed by mylib-x)
both in the ./stage tree and in the /usr/ prefix of the host system
where I prepare the snap.
Is there a way to tell snapcraft to do so?
It should be similar to the way one can use 'build-packages' to
install deb packages on the build host.
