problem with building 64 bit program with freeglut

I am trying to build a 64 bit project with freeglut.

I built the freeglut from source with visual studio’s configuration setting to x64.

then I added the newly built freeglut.lib as source files to my VS project. However, when I built my project with x64 setup, a link error occures saying

cannot open file ‘glut32.lib’

Why does the glut32.lib happen to be here?

It turns out that another library I am using was built with glut32.lib…
