Some CTests require installation to pass

[robbietuk]

This is mostly for documenting the issue. I am running from Clion and a number of CTests (including test_data_processor_projectors) are failing because I haven't installed STIR, just built it. The issue relates to ${STIR_install_location}/share/stir/config/radionuclide_info.json not existing.

The obvious solution is to install STIR once.

Example output:
