Basically yes, if CMake knows exactly which library you want, it can 
order the -L
directories in such a way that you will get the right ones.   It is also 
better for the user
because they will be able to put the path to the library in the cmake 
cache at configure
time.   Not just a path to a directory, but the full path to where the 
library actually is.
