[FEA] CUDF_VERSION in cudf.h ?

[OlivierNV]

Is your feature request related to a problem? Please describe.
Changes to cudf functionality may break existing code that relies on cudf. The lack of versioning makes it difficult to have a code base that could support multiple cudf versions.

Describe the solution you'd like
Seems like a CUDF_VERSION, perhaps along with CUDF_VERSION_{MAJOR|MINOR} definitions would be useful. Would also be useful for cudf-io writers for putting cudf version in parquet/orc files.

I believe this is resolved, including CUDF_VERSION, CUDF_VERSION_MAJOR and CUDF_VERSION_MINOR

I don't believe that this exists yet.

@robertmaynard isn't this trivially solvable now with https://docs.rapids.ai/api/rapids-cmake/stable/command/rapids_cmake_write_version_file/?

[robertmaynard]

Rapids-cmake would provide the major, minor, and patch defines. That should be sufficient for consuming projects
