The name of the property is slightly misleading. 
This property is used when compiling shared libraries under windows, 
there always a different compile flag has to be used when compiling the 
shared lib itself (as opposed to compiling software which links to this 
lib). 
 
Current cmake cvs has a target property "COMPILE_FLAGS", this is probably 
what you want.
