You almost certainly do not want a multiple target rule, because that
would make *each* ${TARGET} depend on *all* the matching .F90 source
files: changing *any* source file would require recompiling *all* the
target files!

Instead, I think you want just a static pattern rule, such as

${TARGET}: %: %.F90 ${OBJECT}
        ...
