At the end of the day, you need to direct your linker to find the 
libraries you want it to link with, there are options to add search 
paths to the linker call (or you could add the explicit path of each 
library), which you would use to point to your locally built version of 
the libraries.  Once you do that and you get linker errors, paste those 
to pastebin and link here I guess.
