[CMake] Allow '-devX' tags

-devX tag may be required when e.g. a first -dev tag was "replaced"
with new patch release incoming from stable branch into main.
E.g., at this moment, the main branch is introduced as v0.10.1-...
instead of v0.11.0-dev... and this is not desired.

 - For major/minor release, when release is done, add an extra "dev" tag on the `main` branch:
   - `git tag -a -s -m "Development version $VERSION+1" v$VERSION+1-dev`
     - for example, when `v0.1.0` is released, the dev tag would be `v0.2.0-dev`
+    - if needed, further in time, an extra dev tag can be introduced, e.g. `v0.2.0-dev1`
   - This way, the `main` branch will introduce itself as the next version
