simex requires ocelot

When I try to import

from SimEx.Calculators.CrystFELPhotonDiffractor import CrystFELPhotonDiffractor

I've got the following error:

Thanks to @JunCEEE, the solution was to turn on the DUSE_GenesisPhotonSource in the install.sh. But it's impossible to guess this. There must be an error message about this, or some similar mechanism.
