coin_qtbase_build_template_v2.yaml did not exist. The build instructions were directly embedded into
module_config.yaml and did not support repos outside of qtbase, also no cross-compilation.
coin_qtbase_build_template_v2 introduced support for building other repos, and also enabled
build cross-compiling targets like Android and iOS.
A bit later the template gained the ability to build qemu cross-compiling configurations.
The counterpart to qtbase to build other repositories is coin_module_build_template_v2
Test templates
coin_module_test_template_v1 did not exist. The test instructions were directly embedded into
module_config.yaml and did not support repos outside of qtbase, also no cross-compilation.
coin_module_test_template_v2 introduced support for building tests for other repos, and made
sure not to build and run tests on cross-compiling configuration. A bit later the template gained
the ability to build and run tests for qemu cross-compiling configurations.
coin_module_test_template_v3 changed the run test instructions to not ignore the exit code
and thus enforce that tests pass in the CI.
