When building standalone cmake fails as follows:

CMake Error at /home/users/david.davies/cylc-run/mi-bg854/share/installs/ioda-spicesystem/lib64/cmake/ioda/ioda-targets.cmake:105 (set_target_properties):
The link interface of target "ioda" contains:

NetCDF::NetCDF_CXX

but the target was not found. Possible reasons include:

* There is a typo in the target name.
* A find_package call is missing for an IMPORTED target.
* An ALIAS target is missing.
