Thank you, Eli. 
I tried GPATH: This will build the *.o files (whether they are up to 
date or not), but it will never link them (no such file...).
VPATH will only build them when needed, but it won't link.
I even tried both VPATH _and_ GPATH, but I had no luck.

OK, now we're getting somewhere. I had tried something similar, but 
wasn't smart enough to change the rule 
%.o : %.cpp to 
objs/%.o : %.cpp

I had to change -o objs/$@ to the old -o $@ in the last line because 
the assembler tried to create, e.g., objs/objs/main.o 
But now it is finally working! It might not be the most elegant 
solution under the sun. But my project isn't that big, so I guess it 
is worth the effort.

Again: Thank you!
