Linking and Add Executable on CMAKE?

I am learning CMAKE and the example I have has both link_directories before and after add_executable. My question is: how does the process work? Which is supposed to go first and what is the purpose of one going before the other?

Not sure if this order matter. Probably not. "link_directories" will tell the compiler where to look for the libraries you desire to use. The names of the libraries you put in "target_link_libraries" command.

Actually, with CMake, "link_directories" is not used too often. Usually you use a module script to find your libraries with "find_package" (e.g., findCUDA, findJPEG, etc...) and pass to "target_link_libraries" the variables defined by these scripts containing the full path of each library.
