AUTOMOC used to fail to generate ``moc_predefs.h`` when ``ccache`` was used as a compiler starter by e.g. configuring a project with the environment variable CXX="ccache g++". The reason was that ``CMAKE_<LANG>_COMPILER_ARG1`` wasn't respected in the definition of ``CMAKE_<LANG>_COMPILER_PREDEFINES_COMMAND`` for various compilers. This is fixed by this patch. Fixes #17275.
