Well, maybe previously I did not describe the problem in a good way. I 
played around a bit and now it works but for one library only.
If I use only one library (Foo and FooD respectively) to link to Bar (as 
indicated above) it works; if I use two libraries and do it like that,

TARGET_LINK_LIBRARIES(Toe debug BarD FooD optimized Bar Foo)

it does not work, giving me the errors already described above. BUT! If 
I do it like that

TARGET_LINK_LIBRARIES(Toe debug BarD debug FooD optimized Bar optimized 
Foo)

it works - I'm pretty sure this is not the usual way to do it. Whatever 
I tried, using quotation marks, colons or semicolons to indicate a list 
of libraries does not work...
