[CMake] ctest_update with git fetch --tags (was: ctest & git submodules)

[NoRulez]

Thank you very much.

The goal is to have a nightly/continuous build with the tagged version number.

Without the "--tags" option it is only working if we push the changes after tagging.

With the "--tags" option it is now also possible to move/overwrite tags which gets then updated.

In the projects CMakeLists.txt file we get the current tag/version with "git describe --tags"

Maybe there would be alternatives but currently this is working fine. But we are open for suggestions.

Best Regards
