That's odd... maybe that header's not in the conda package yet? These are the paths CMake is using:

-- CUDF: CUDF_HOME set to /var/lib/jenkins/workspace/rapidsai/gpuci/cuspatial/prb/cuspatial-gpu-build_3/cudf
-- CUDF: CUDF_LIBRARY set to /opt/conda/envs/gdf/lib/libcudf.so
-- CUDF: CUDF_INCLUDE set to /opt/conda/envs/gdf/include
