I've erred on the side of caution and treated the COPYING-CMAKE-SCRIPTS
license (a BSD-3-Clause variation) as its own distinct license.

This makes it possible for projects to incorporate D-Bus as a CMake sub-project in a larger CMake project.
Before this PR, doing so would result in many errors.
This is because CMAKE_SOURCE_DIR and CMAKE_BINARY_DIR would point to directories above the D-Bus project.
Using paths relative to the project directory, PROJECT_SOURCE_DIR and PROJECT_BINARY_DIR, corrects for this.
