Provides the following variables:
* `NetCDF_FOUND`: Whether NetCDF was found or not.
* `NetCDF_INCLUDE_DIRS`: Include directories necessary to use NetCDF.
* `NetCDF_LIBRARIES`: Libraries necessary to use NetCDF.
* `NetCDF_VERSION`: The version of NetCDF found.
* `NetCDF::NetCDF`: A target to use with `target_link_libraries`.
* `NetCDF_HAS_PARALLEL`: Whether or not NetCDF was found with parallel IO support.
