AHHHH!!!

This is the most misunderstood warning of all times....  :)


You do not have to use full paths for all libraries now.
You do not have to use full paths for all libraries now.

For system libraries like this one it is much safer to just list them. 
If you set the policy to NEW, it will just work with no warnings. The 
warning says that it maybe a problem, but to try it as NEW, and if it is 
not a problem, then you are good.

For this case I would recommend changing ws2_32 to not being found.  It 
is a standard library that the compiler should be able to find the 
appropriate version of.
