Study how Boot2Qt currently works, and how to run the build process in CI

In order to get Yocto support to QT Cloud, we need to be able to produce Boot2Qt compatible binaries in CI. In this phase, we need to restrict the support for only Boot2Qt -distribution and the supported embedded platforms need to be defined.

As an initial PoC:

• Study, how the build process for Boot2Qt currently works in Qt Creator. Create a simple example project, build, and deploy it to actual embedded HW
• Check the existing work on containerizing the toolchain, and check if the Dockerfiles from there can be used in CI, as-is or with some modifications
• Build the example project from step 1 in CI, and verify that the end result works on actual embedded HW.
