xserver-xorg-dev is:

This package provides development files for the X.Org (‘Xorg’) X server. This is not quite the same as the DDK (Driver Development Kit) from the XFree86 4.x and X.Org 6.7, 6.8 and 6.9 series of servers; it provides headers and a pkg-config file for drivers using autotools to build against.

Unless you are developing or building a driver, you probably want xserver-xorg and/or xserver-xorg-core instead.
