Linux dockerized build and AppDir generation for compilation errors
Also added AppImage TODOs, basic setup for MacOS and Windows but they
still need work to have at least validation running
Temporary disable CPP windows/mac until limitations are
addressed in a follow up commit
Extra: add build configuration fixes for rest of the platforms
closes: #5998
Considerations
- Use versioned files. Versioned Qt CMake APIs are disabled to force explicit calls and say that we don't support older `QT`s
- Don't use blobbing. Use `target_sources` and `qt_target_qml_sources`
- Distribute `CMake` definitions closer to the context: main folders with their own `CMakeLists.txt`
- Everything in libraries under `Status` namespace for cleaner code.
- Includes are exposed with Module folder externally and without prefix internally
- File/Folders name matches definitions they contain for uniformity that leads to cleaner code
- All source files (cpp, qml, js ...) have to be added to one of the CMakeLists.txt files to be tracked by CMake build system.
- Use BUILD_DEBUG, BUILD_RELEASE and BUILD_DEVELOPMENT variables from Helpers library
- Avoid Include directories. Not needed anymore CMake `target_*` APIs handles this through `INTERFACE`, `PUBLIC` and `PRIVATE` scope identifiers
- `StatusQ` is meant to be compiled as an external library, therefore StatusQ tests are kept inside its own directory
- Forced CMake version to `3.21` for the latest features and fixes. It is desired to be kept as recent as possible due to its backward compatibility. Following Qt's shipped version might be an option
- Depends on status-go changes to allow forcing of arm for apple silicon
Found limitations to CMake Qt API with Qt 6.3
- Having `0` as major version when using `qt_add_qml_module` doesn't work. Qml engine reports loading the `qmldir` but won't load the plugin library and no error is reported outside that exposed types are not found.
- `qt_target_qml_sources` doesn't work now, it generate a double copy error when deploying qml files in bin-directory. For now we stick with adding files using `qt_add_qml_module` central place
- Need to add `OUTPUT_DIRECTORY` to `qt_add_qml_module` to use the workaround
- If `MACOSX_BUNDLE` target property is set breaks importing of QML files. Disabled until fixed or workaround found
- For an unknown reason application executable tries to include the `QML_ELEMENT` include files, therefore for now I include all the C++ qml elements in INTERFACE
