There's nothing random. Let's take kcoreaddons and attica as examples:

KCoreAddons/KAboutData contains #include "kaboutdata.h"
Attica/Attica/AccountBalance contains #include "attica/accountbalance.h"

The namespaced camelcase headers just follow what is done for the files they include.
and if you need another reason:

    # ls **/Plugin
    kabc/include/KF5/KABC/KABC/Plugin                              kontactinterface/include/KF5/KontactInterface/KontactInterface/Plugin  ktexteditor/include/KF5/KTextEditor/KTextEditor/Plugin kdelibs4support/include/KF5/KDELibs4Support/KDE/KParts/Plugin  kparts/include/KF5/KParts/KParts/Plugin

If you use these build dependencies, what should happen if you just #include <Plugin> ?

I also don't see a reason why to install into KPIMUtils/KPIMUtils/...?
