I know this is a simple question, but I'm really stuck here; I even bought a book and made what was written there, but it didn't help.

I wan't to use the library wavelet2d from here. I'm using Visual Studio 2008. The documentation tells me that the files:
are needed. So I copied them to the source folder of my program. Then I right clicked on my project in the project-explorer and chose add-> existing element and chose to add wavelet2d.lib.

I tried to include a folder where I copied the files as an additional includepath, but that changed nothing.
What is going wrong? Do I have to #include something in my program? The functions of the lib aren't found.
I'm sorry if the names of the buttons in VS2008 I used are wrong, I'm german and I just translated the words.
Thanks in advance!

Best regards,
