feat(cmakev2/build): set PROJECT_VER build property

Browse Source 
Initialize the PROJECT_VER build property based on the following
precedence.

1. The PROJECT_VER environment or CMake variable.
2. The version.txt file located in the top-level project directory.
3. The VERSION argument, if provided, in the project() macro.
4. The output of git describe if the project is within a Git repository.
5. Defaults to 1 if none of the above conditions are met.
