How to use libpng in Visual Studio?

Question

I am using boost generic image library and it requires libpng. I built libpng and obtained the files libpng.lib, zlib.lib and libpngd.lib. When I tried to compile my project, Visual Studio gives a fatal error

fatal error LNK1120: 21 unresolved externals

with a bunch of unresolved external symbols like _png_set_sig_bytes and _png_read_row. What's going on here and how to solve it?

From MSDN:

To add .lib files as linker input in the development environment

    Open the project's Property Pages dialog box. For details, see Setting Visual C++ Project Properties.

    Click the Linker folder.

    Click the Input property page.

    Modify the Additional Dependencies property.

You must do this; explicitly specifying "libpng.lib", "zlib.lib" and "libpngd.lib" in your .exe's link command.
