Typically you need to do 5 things to include a library in your project:
1) Add #include statements necessary files with declarations/interfaces, e.g.:
#include "library.h"
2) Add an include directory for the compiler to look into
-> Configuration Properties/VC++ Directories/Include Directories (click and edit, add a new entry)
3) Add a library directory for *.lib files:
-> project(on top bar)/properties/Configuration Properties/VC++ Directories/Library Directories (click and edit, add a new entry)
4) Link the lib's *.lib files
-> Configuration Properties/Linker/Input/Additional Dependencies (e.g.: library.lib;
5) Place *.dll files either:
-> in the directory you'll be opening your final executable from or into Windows/system32
