Build dependency missing from readme

[deniz-unal]

The project's build configuration requires git to be installed on the system, but it is currently not listed in the dependencies section of the readme file.
In ProjectGitVersion.cmake, the build tries to locate Git with the REQUIRED flag. If Git is not present, CMake fails with this message:

CMake Error at /usr/share/cmake-3.28/Modules/FindPackageHandleStandardArgs.cmake:230 (message):
  Could NOT find Git (missing: GIT_EXECUTABLE)

README.md should be updated to include Git as a build dependency.

Fixed -- that code was buggy and "almost unused", so you can now build without git. We might revisit that in future. Thanks for the bugreport.
