This is basically always wrong. Since you usually pass absolute paths to 
target_link_libraries() this doesn't help in any way but may cause trouble. 
Just don't do it.

You already did that before.

Since CMAKE_RUNTIME_OUTPUT_DIRECTORY is already set you should not need that 
anymore.

These br* things are be created by add_library(... shared ...) in your 
project, no? Then this should work if you had previously set 
CMAKE_LIBRARY_OUTPUT_DIRECTORY to bin or so.
