Debugging CMake build-time script mode calls from `add_custom_command`

Recently, I wanted to understand what was occuring in some CMake script run by LLVM's CMake build system. It runs at build time via add_custom_command, invoking CMake in script mode (-P). I was trying to find out what happens in the script when ${llvm_source_dir} is empty. The internal details of GenerateVersionFromVCS were a bit hard to follow.

  set(version_inc "${CMAKE_CURRENT_BINARY_DIR}/VCSRevision.h")
  set(generate_vcs_version_script "${LLVM_CMAKE_DIR}/GenerateVersionFromVCS.cmake")
