Note that you still have to enable the camera, which is a matter of adding start_x=1 to /boot/config.txt and explicitly committing at least 128 MB of RAM to the GPU.

For the raspicam stuff, you only need what's in the hardfp/opt/vc/ directory. Beware there's also an opt/vc (no hardfp), and readelf seems to confirm that, as implied, these are not compiled with floating point support (which is likely significant for graphics applications, although most of the heavy lifting should be done on the GPU anyway).
