The cc65 library build system is designed to call sub-makes in direct sub-directories of 'libsrc' only (meaning that sub-sub-directories are not supported). The GEOSLib source files however are organized in sub-directories of the 'libsrc/geos-cbm'. This mismatch was up to now handled by replicating the cc65 library build system functionality to allow for individal sub-makes in each 'libsrc/geos-cbm' sub-directory. This is unnecessarily hard understand and causes additional maintainance effort.

Now the whole GEOSLib is built in a single make instance running in 'libsrc/geos-cbm' - which is just what the cc65 library build system can handle. The 'libsrc/geos-cbm' sub-directories still contain Makefiles. However those files only define the set of object files to create from their sub-directory and get included into the 'libsrc/geos-cbm' Makefile.
