As they shouldn't.  As the option says, it's a prefix, i.e. it will look for 
lib/ and include/ within that directory.  So specifying /usr/local/lib as a 
prefix will go searching for /usr/local/lib/lib and /usr/local/lib/include, 
which clearly won't work!

At least you've located where things are.  Since /usr/local is a standard 
location on most systems, I don't see why you need to specify any additional 
options, but -DCMAKE_PREFIX_PATH=/usr/local in theory should work.
