The INSTALL statement has _nothing_ to do with linking the executable.

Did you build it using ADD_LIBRARY?
If yes:
PROJECT(HELLO)
ADD_LIBRARY(Hello foo.c)
ADD_EXECUTABLE(HelloBin bar.c)
TARGET_LINK_LIBRARIES(HelloBin Hello)

ADD_LIBRARY defines the TARGET "Hello" in the above lines. That should  
link to the local libHello even if you have another version in the  
system.
