v5.1.4/5.2 problems parsing its own code?

[René J.V. Bertin]

Commit e871b84891d419908a029d017d15af70540cb478 seems to have improved parser behaviour a bit. As an example:

- when usins CMake Server import, the parser now only doesn't find the cmakebuilderconfig.h and ui_cmakebuildsettings.h headers in cmakeutils.cpp and cmakepreferences.cpp .

- when using JSON-based import, the parser doesn't find the interfaces/icore.h , KLocalizedString, KMessageBox and KJobWidgets headers in cmakepreferences.cpp and complains about undeclared QString and QStringLiteral in cmakeutils.cpp 

(Turning off cmake server import is trivial using a wrapper script around cmake.)
