You probably want to erase depend since you are only
appending to it. You need more semicolons and use double
quotes around the *.cpp in the find command and on the final
echo. One semicolon after each statement:
depend: $(SOURCES) $(HEADERS)
cat </dev/null >depend ; \
for file in `find . -name "*.cpp"`; do \
filewosuffix=`echo "$$file" | sed 's/.cpp//g'` ; \
g++ $$file -MT '${OBJDIR}/"$$filewosuffix".o' >> depend ; \
echo "$${CXX} -c $${CXXFLAGS} $${DEFS} -o $$@ $$<" >> depend ; \
done
(untested)
