Leon, would you please post your probe code to the mailing list? I am
generally interested in Qbs Conan integration and would like to see how
others do it.

If you know what architecture your project will be built for, specify a
project property and set this from command line (or in Qt Creator).

Note that such an architecture-agnostic Conan probe breaks if you are going
to multiplex a product over different architectures. In that case it would
better to put the probe into the product or even a separate module. Make
every product in your project depend on that module. The probe should only
run a single time for the whole project. Then you should be able to use
properties from the qbs module as inputs of the probe.
