When?

The truth is that I don't know where to get this information, but I would like to collaborate in the creation and updating of the document. If you have any information about it that you can provide me, I will try to see what I can build.

The hooks are executed with the CU_RUN_HOOK method of our cmake library and they are just hooks that run in a certain time of the build phase to allow you injecting some cmake operations in modules to extend the build phase.
You can check them with the link above or search one by one in our codebase and see where they are executed. I have used them a lot in past for the AzerothShard module

I have been learning a little bit about them, not so much the cmake ones, but the ones of the emulator itself, and how they can be useful, for example, when creating modules. In fact, for the loot module in area, I was told that I would need one, as well as for another idea I had in mind, about the possibility of allowing the mission items to have a 2048 flag, and that way, all members of the group, can get that item (that today I "solved" with SQL, adding the flag, but it is not something blizzlike, so at some point, I would like to solve it by implementing perhaps a module and a hook).
