Hi Drew, a custom target can do literally anything, it's just a buildsystem wrapper for running arbitrary executables; or often not even that, and is just a collection of custom commands. There is nothing CMake automatically does with the properties [INTERFACE_]INCLUDE_DIRECTORIES set on a custom command.
Note that if you need the properties set for some reason (i.e. if your custom command/target code uses them for something), you can still set them just fine using set_property() or set_target_properties(). However, I expect this to be a very rare thing to do, so I think it's OK target_include_directories() actually errors out on custom targets. IMO it's much more likely that a non-custom target was intended. (Note that I am just an ordinary CMake user, so the above is in no way "official.")
