I don't want to argue about the requirement, but using the
VPATH patch for depend2.am (see the archive of this list)
it would be possible to write

        VPATH = ${srcdir}:${srcdir}/dir1:${srcdir}/dir2
        lib_LIBRARIES = libGeomExakt.a
        libGeomExakt_a_SOURCES = a.cpp b.cpp

Please note that there are pitfalls with VPATH, e.g. for
the search path of the header files, when using

        #include "myheader,h"
