This can be convenient for linking against the 3rd party libraries, etc. since CMake will already know about the 3rd party targets and CMake will also build them with the same settings as the rest of your build. If you want, you can use ExternalProject to download the source code at configure time, a technique I recently mentioned on this list. You can find the article about that approach (with Google Test as the example) here: http://crascit.com/2015/07/25/cmake-gtest/ -- Craig Scott Melbourne, Australia http://crascit.com
