The answer is rather simple: don't use link_directories(). If you use it and it gives you trouble that means that you don't understand what it does and that means that you don't need it. Really. Use target_link_libraries() with a full path to the library you want to use and let CMake do everything else. Can we please get a big fat warning message into the link_directories() documentation telling people that if they come from Makefiles or whereever they should not use this function as this works different than in plain makefiles and is usually a bad idea to use? I'm often doing support in #cmake on Freenode and this is likely the most misunderstood concept of everyone coming from plain Makefiles. Eike
