The problem is that this model does not scale. Now there is one device
using SailfishOS, next June there will be two...
Hopefully there will be more in one year.
So you want to make one build for each model that will use SailfishOS
in the future?
I think Jolla hopes to license the OS to other vendors. If they
succeed, optimization s targeted to single devices will not be
The best option is to build the asset in a scalable format (or ship it
at high res) and then render it at install time...
Like what has been proposed for the icon scaling.

Well, I think the easiest thing to do is do out-of source builds, and
since the target configuration
qmake -config sailfishos
qmake -config blackberry
Then if you want to have different assets, you can do this as well...
But it makes no sense to ask for a generic way to do that.
In the end, the Qt platform for sailfish os is indeed simply Linux, or
if you want Linux+Wayland.
The rest of the dependencies should be checked package for package:
So on linux, check if there is libsailfishapp, and build the sailfish version.
Check for... Mir, and build for Ubuntu.
Or build for a desktop Linux if you do not find mobile specific libraries.
