CMake link to external library

Question

How to get CMake to link an executable to an external shared library that is not build within the same CMake project? Just doing `target_link_libraries(GLBall ${CMAKE_BINARY_DIR}/res/mylib.so)` gives the error ``` make[2]: *** No rule to make target `res/mylib.so', needed by `GLBall'. Stop. make[1]: *** [CMakeFiles/GLBall.dir/all] Error 2 make: *** [all] Error 2 (GLBall is the executable) ``` after I copied the library into the binary dir `bin/res`. I tried using `find_library(RESULT mylib.so PATHS ${CMAKE_BINARY_DIR}/res)` Which fails with `RESULT-NOTFOUND`.

Accepted Answer

Set libraries search path first:

```
link_directories(${CMAKE_BINARY_DIR}/res)
```

And then just do

```
target_link_libraries(GLBall mylib)
```
